Question
In the question, two quantities I and II are given. You
have to solve both the quantities to establish the correct relation between Quantity-I and Quantity-II and choose the correct option. I. 2x2 + 7x + k = 0 II. (ay + b)2 = 0 Find the value of “k”. When it is given that: 1. Larger roots of equation I is equal to larger root of equation II. 2. Smaller root of equation I is -2.Solution
From condition 2, we will put the value of x = -2 in equation I, 2x2 + 7x + k = 0 => 2 × (-2)2 + 7 × - 2 + k = 0 => 8 – 17 + k = 0 => k = 6
