Question

Fatore
4ax-8ay
Fatore
x²-64
Fatore
ax-ay+2x-2y

Answer 1

Fatore4ax-8ay ==> 4a(x-y)
Fatore
x²-64 = (x + 8)(x - 8 )
Fatore
ax-ay+2x-2y ==> a(x - y) + 2(x - y ) ==> (x - y)( a + 2 )

Answer 2

$4ax - 8ay \\ \\ a(4x - 8y) \\ \\=> 4a(x - 2y)$

====

$x^{2} -64 \\ \\ (x - 8)(x+8)$

====

$ax +ay + 2x - 2y \\ \\ a(x + y) + 2x -2y \\ \\ x(a + 2) + ay -2y \\ \\ => (x - y)(a+ 2)$
