Factorize abx2 + 8y - 4bx - 2axy
A
(ax - 4)(bx - 2y)
B
(ax + b)(x - 8y)
C
(ax - 2y)(bx - 4)
D
(bx - 4)(ax - 2y)
E
(abx - 4)(x - 2y)
Verified Correct Answer: A.
Step-by-Step Mathematical Solution
abx2 + 8y - 4bx - 2axy = (abx2 - 4bx) + (8y - 2axy)
= bx(ax - 4) 2y(ax - 4) 2y(ax - 4)
= (bx - 2y)(ax - 4)
