II. 77y² + 155y + 72 = 0
I. 96x² + 52x - 63 = 0 96x² + 108x - 56x - 63 = 0 12x (8x + 9) - 7(8x + 9) = 0 (12x - 7) (8x + 9) = 0 x = 7/12 , - 9/8 II. 77y² + 155y + 72 = 0 77y² + 56y + 99y + 72 = 0 7y(11y + 8) + 9(11y + 8) (7y + 9) (11y + 8)= 0 y = - 9/7 , - 8/11 Hence no relationship can be established.
