Webx 2 + x − 12 = 0. Therefore, we can set the right hand side equal to any number we want. We usually set it equal to zero because this helps to solve later. Example: ( x + 3) ( x − 2) = 6. vs. ( x − 3) ( x + 4) = 0. The second one is easier to solve … WebMar 6, 2014 · At least for quadratics, if you want to solve (for example) x 2 + 5 x + 8 = 2, it is much easier to subtract 2 from each side, and factor: x 2 + 5 x + 8 − 2 = 0 x 2 + 5 x + 6 = 0 ( x + 2) ( x + 3) = 0 Here is the key: the only way for a product of numbers ( x + 2) and ( x + 3) to be equal to zero is for one to be zero.
