Question
I. x2 - 11x + 24 = 0 II. y² - 5y + 6
= 0 In each of the following questions, there are two equations. You have to solve both equations and mark the correct answer.Solution
I. x2 – 11x + 24 =0 => x2 - 8x - 3x + 24 = 0 => x(x - 8) - 3(x - 8) = 0 => (x - 8) (x - 3) = 0 => x = 8, 3 II. y² - 5y + 6 = 0 => y2 - 2y - 3y + 6 = 0 => y(y - 2) - 3(y - 2) = 0 => (y - 2) (y - 3) = 0 => y = 2, 3 Hence, x ≥ y.
