To solve a polynomial inequality or a rational inequality, our first step is to place our inequalities in general form, which means that we'll have our function here on one side and then our sign here, which can be less than equal to, greater than, and doesn't matter on there whatever that equation gives you, that inequality gives you.

And on the other side, we'll have it set to zero.
00:53
So if this side is not equal to zero, we'll subtract this number from both sides.
01:04
And then we'll have our general form.
01:07
Our next step would be to find the zeros of our function or where it's undefined.

Zeros and undefined values.
01:29
So to do this, we need a factor.

Sometimes we need to use our function x equals negative b plus or minus the square root of 4ac...
