Given that x = 2 and y = -(frac{1}{4}), evaluate (frac{x^2y – 2xy}{5})
-
A.
zero -
B.
(frac{1}{5}) -
C.
1 -
D.
2
Correct Answer: Option A
Explanation
Given; x = 2; y = (frac{-1}{4})
= (frac{x^2y – 2xy}{5})
= (frac{2^2(frac{-1}{4}) – 2(2)(frac{-1}{4})}{5})
= (frac{4(frac{-1}{4}) + 4(frac{-1}{4})}{5})
= (frac{1 + 1}{5})
= (frac{0}{5})
= 0
