Question
I. x2 - x - 56 = 0 II. y2 -
20y + 96 = 0 In each of the following questions, there are two equations. You have to solve both equations and mark the correct answer.Solution
For x2 - x - 56 = 0 Let's solve your equation step-by-step. x2 - x - 56 = 0 (x+7) (x-8) x + 7=0 or x - 8 =0 x = 7 or x = 8 For y2 - 20y + 96 = 0 y2 - 20y + 96 = 0 (y - 8) (y - 12) = 0 y - 8 = 0 or y - 12 = 0 y = 8 or y = 12
