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!
