To do this, first you want to notice that there is no number in front of the x^2.
This will not work on its own if there is
Find 2 numbers that multiply to 2 and add to - 3
-3 is in front of the x and 2 is alone in the equation so those are the numbers you are using
-2 and - 1 are the only whole numbers that do that
-2 + - 1 = - 3
-2 * - 1 = 2
