Expression as product is :

x^3+x^2y–4y–4x =
(x-2)(x+2)(x+y)

y^2(2y–5)–8y+20 =
(y-2)(y+2)(2y-5)

Explanation:

Here we need to write , following expression as product:

x^3+x^2y–4y–4x


x^3+x^2y-4y-4x


x^2(x+y)-4y-4x


x^2(x+y)-4(y+x)


(x^2-4)(x+y)


(x-2)(x+2)(x+y)

y^2(2y–5)–8y+20


y^2(2y-5)-8y+20


y^2(2y-5)-4(2)y+4(5)


y^2(2y-5)-4(2y-5)


(y^2-4)(2y-5)


(y-2)(y+2)(2y-5)
