and this question. We just want to list the values of the variables foolishness. Rational fraction is undefined, and all we have to do is just find where the domino equal zero. So we just say 380 And of course, we can already see that when able zero, our expression will be undefined.

in this exercise you just wanted list the values of the variables for which the rational expressions undefined and all I have to do for this. Is that the denominator equal to zero? So if you do that, we get a B equals zero. And for the sequel zero, we can say that either Engel zero or vehicle zero, and to answer this question would just say that eight cannot equal zero economical zero because that would give us an undefined fraction, as that would make the general major zero.

Okay, so we are asked to list the values of the variables that makes this rational expression here on defined. So first, what we&#x27;re gonna do is we&#x27;re gonna factor this denominator. And so we leave our five up here and the five doesn&#x27;t really matter. So if you want to admit that, that&#x27;s fine, too. We see here that each one of these hasn&#x27;t act. So first, let&#x27;s take out the X. And then I&#x27;m left with X squared minus five x minus sechs. And now we have X and then we&#x27;re going to factor this here. Right? So when I have a negative, I know first I start with the ex Is this is a positive. So I have X Times X And then whenever I have a negative, I have to have a positive and the negative and my factors of six that are going to then we win. When we take the difference, come to five is six and one, because two and three would only work if this was positive. So here we have the six and the one. The bigger number has got to be negative. So we put the six in front of the negative, the one over here. And then we set each one of these variable. Each one of these factors here equals zero. So we have that X is equal to zero. I have X plus one equals zero, and I have X minus six equal to zero. So if you could do this in your head, that&#x27;s great too. But we know that when we solve for this, we subtract one on both sides and I get X is equal to negative one. And when I saw for this, I add six to both sides. So I get X is equal to positive sex. So six negative one and zero all make this rational expression undefined because they will make the denominator zero.

in this exercise. We just want to find the values of the variables for which this rational expressions on the find and I&#x27;ll have to do for this. It&#x27;s a regional mayor equal to zero, so we&#x27;ll have to. A minus seven equals zero at seven full size, we get to a vehicle seven divide by two when we get a equals seven over to so that we can say that a cannot equal seven over to If we want to have this expression be defined because of equal seven over to, we&#x27;re gonna zero in the denominator and therefore it is undefined.

Martha Richards · Answer

All right. So we&#x27;re given this expression here and were asked to, uh what numbers? What? What values for the variables here will cause this expression to be undefined. And so here, that&#x27;s when the denominator it is undefined when the denominator is equal to zero. And so all we do is set. The denominator equals zero and we get solving for X, we get X is equal to negative five. So for the value where X is equal to negative five this expression he up here is on defined.

So we&#x27;re given this rational expression and were asked to list the values of the variables that make this undefined. And so what we&#x27;re going to do first is factor the denominator. So I still have the B plus three in the numerator and the denominator. I always write out the things that I know for sure. I know that in order to get b squared, I&#x27;ve gotta have be times be remember always gonna foil this back out and then I have a negative. So I have to have one positive and one negative because that for foil, remember that l The last is the last to hear. And still, in order to get a negative for this number, I&#x27;ve gotta multiply a positive time, the negative. And now what are the factors of six? So the only factors of six or two and three and six and one And when I take the difference, remember when I have two different signs, I&#x27;m taking the difference. The difference here is a five, and the distance here is a difference. Here is one. So this is the two factors and because I have a positive here, that means the bigger numbers gotta go here and the smaller number here. And the other thing that typically happens with most of these problems is that what&#x27;s on the numerator ends up also being in the denominator. So you should have been able to guess here that this was gonna happen as well. So now that we&#x27;ve got this factored out, remember when I multiply any number time zero this If this is zero, this become zero. If this is zero, this become zero. And so what we do here is we set both of these equal to zero and sell for B. So this 1st 1 here, when I solve for B, I get that B is equal to a negative three and then this one here, B is equal to a positive to cause I add to to both sides. So for both of these values here, this rational expression right up here will be undefined because those numbers in the denominator cannot be zero
