Question
I. 99x² + 161 x + 26 = 0
II. 26 y² + 161 y + 99 = 0
Solution
I. 99x² + 161 x + 26 = 0 99x² + 143x + 18x + 26 = 0 11x (9x + 13) + 2 (9x + 13) = 0 (11x + 2) (9x + 13) = 0 ∴ x = -2/11 , -13/9 II. 26y² + 161y + 99 = 0 26y² + 18y + 143y + 99 = 0 2y (13y + 9) + 11(13y + 9) = 0 ∴ y = -11/2 , -9/13 Hence, relationship cannot established between x and y.
