Evaluate frac xy 2 - x 2y x 2 - xy 1 When x -2 ... - JAMB Mathematics 1991 Question
Evaluate \(\frac{xy^2 - x^2y}{x^2 - xy^1}\) When x = -2 and y = 2
A
3
B
-\(\frac{3}{5}\)
C
\(\frac{3}{5}\)
D
-3
correct option: d
\(\frac{xy^2 - x^2y}{x^2 - xy^1}\)
= \(\frac{(-2)(3)^2 - (-2)^2(3)}{(-2)^2 - (-2)(3)}\)
= -30
= -3
= \(\frac{(-2)(3)^2 - (-2)^2(3)}{(-2)^2 - (-2)(3)}\)
= -30
= -3
