Question
l. x2 - 16x + 64 = 0 II.
y2Â = 64 In the following question two equations are given in variables 'x' and 'y' On the basis of these equations you have to decide the relation between 'x' and 'y' and give answer.Solution
ATQ, From l. x2 - 16x + 64 = 0 x2 - (8+8) + 64 = 0 x2 - 8x - 8x + 64 = 0  x(x-8) - (x - 8) = 0  x - 8 = 0 or x - 8 = 0  Hence x = 8  From II: y2 = 64  Let's solve your equation step-by-step. y2 = 64 Step 1: Take square root. y = ± √64 y = 8 or y = − 8 Hence, x ≥ y
