Question
I. x² - 19x + 84 = 0 II. y² - 25y + 156
= 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 - 19x + 84 = 0 Pairs are: -12, -7 So by changing its signs & dividing by a i.e.1, we will get x = 12, 7 II. y² - 25y + 156 = 0 Pairs are: -13, -12 So by changing its signs & dividing by a i.e.1, we will get y = 13, 12 Hence, x ≤ y.
