Question
I:Â x2Â - 33x + 242 = 0 II:Â
y2Â - 4y - 77 = 0 Direction: In each of the following question, two equations are given. You have to solve both the equations to find the relation between x and y.Solution
From I => x2 - 33x + 242 = 0 => x2 - 22x - 11x + 242 = 0 =>x(x – 22) -11(x – 22) = 0 => (x – 11) (x – 22) = 0 => x = 11, 22 From II => y2 - 4y - 77 = 0 => y2 – 11y + 7y - 77 = 0 =>y(y - 11) +7(y – 11) = 0 => (y + 7) (y – 11) = 0 => y = -7, 11 Hence, x ≥ y
