Question

factor completely:

5x(4x-y)-4z(y-4x)

Answer 1

(5x-4z)(4x-y) or (5x+4z)(4x-y)??????????

Answer 2

distribute the - sign in the initial equation
or work backward from both answers to find the correct one

Answer 3

please show

Answer 4

I got (5x+4z)(4x-y)

Answer 5

5x(4x-y)-4z(y-4x) => 5x(4x-y) + 4z(-y+4x) is distributing the - sign in the initial equation.
to do it the other way, multiply (5x-4z)(4x-y), then multiply (5x+4z)(4x-y) and see which one is the same as the initial equation

you got it right

Answer 6

thank you for explaining it to me
