Question
I. 8x² + 2x – 3 = 0 II. 6y² + 11y + 4 =
0Solution
I. 8x² + 2x – 3 = 0 Pairs are 6,-4 So by changing its signs & dividing by a i.e.8, we will get x = -6/8, 4/8 = -3/4,1/2 II. 6y² + 11y + 4 = 0 Pairs are 3,8 So by changing its signs & dividing by a i.e.6, we will get y = -3/6, -8/6 = - 1/2, -4/3 Hence, no relationship can be established between x and y.
