Right, so for problem 737, we're given this expression, and we need to find its quotient or factored form using synthetic division.
00:12
So synthetic division works when you're dividing by a binomial, and that binomial in question is written in the form of x minus c, where c is a constant number.
00:26
So in this case, we have the binomial being x plus 3, which means the c must be.
00:34
Negative 3 so that the negatives cancel each other out and with that so we're going to start with the actual division so we're going to write the negative 3 here and we'll make like a corner here to separate it from the other numbers and now we're going to write down each term like in their order so it's going to be 2 5 negative 7 negative 12 so 2, 5, negative 7, negative 12.
01:10
And we have to make sure that it's in the order in which the exponents are decreasing.
01:18
So now we draw a line and we bring the first value down, this 2 down.
01:23
So it's going to be 2 here.
01:25
And then we multiply it by the number we have in the upper left.
01:29
So 2 times negative 3 is negative 6.
01:34
And then we add it with the number above.
01:37
So 5 plus negative 6 is negative 1.
01:40
And then we repeat the cycle...
