Question
I. x² + 11x + 24 = 0 II. y² + 17y + 72
= 0 In the following questions, two equations numbered I and II are given. You have to solve both the equations and give answer.Solution
I. x² + 11x + 24 = 0 x² + 3x + 8 x + 24 = 0 x (x + 3) + 8 (x + 3) = 0 x = - 3, - 8 II. y² + 17y + 72 = 0 y² + 8y + 9 y + 72 = 0 y (y + 8) + 9 (y + 8) = 0 (y + 8) (y + 9) = 0 y = - 8, - 9 Hence, x≥y
