WebWhile correct, one solution method is more logical than the other as it will likely save time or lead to potentially fewer mistakes. Whose method is better and why? Jessica (x-3)² - 16 = 0 (x-3) (x-3) -16=0 x² - 6x +9-16=0 (A) Jessica's method is better since she is distributing (x - 3)² and can eventually use the quadratic formula. Webxar!

WebIt is easy to show x = -2 is a root of the cubic and it factors into (x+2)(x² + x + 1) = 0 (the roots to the quadratic factor are complex, but I don’t even need to write them) The quadratic either has two real roots or two complex roots. It can only share roots with the cubic’s quadratic factor. If it has the same roots it must have form ... Web21. What is the sketch of the graph of the polynomial function y = x x (x² - 5)? 22.

It's easier to start with the +-1 and then the +-2 and so on. When using synthetic division, we must have a remainder of 0 for the dividend to be a zero. Using synthetic division to get our equation to a quadratic, then by factoring the quadratic, we find the roots are 2, -2 ... thinking blocks multiplication and division
