=4x(2x + y) - a(2x - y)

=(2x + y)(4x - a)

Dễ mà bạn!!!

Answer 2

\(8x^2+4xy-2ax-ay\)

= \(\left(8x^2+4xy\right)-\left(2ax+ay\right)\)

= \(4x\left(2x+y\right)-a\left(2x+y\right)\)

= \(\left(2x+y\right)\left(4x-a\right)\)

Answer 3

\(8x^2+4xy-2ax-ay\\ =4x\left(2x+y\right)-a\left(2x+y\right)\\ =\left(2x+y\right)\left(4x-a\right)\)
