Step-by-step explanation:
a) x^2 +xy+8x+8y
x(x+8)+y(x+8) [taking (x+8) as common]
(x+y)(x+8)
b) 15xy-6x+10y-4
3x(5y-2)+2(5y-2) (spilitting the terms and
(3x+2)(5y-2) then taking the
common bionomial)
c) 16x^4-81
(4x^2)^2-(9)^2 [a^2-b^2=(a+b)(a-b)]
(4x^2-9)(4x^2+9)
d) 3a^4-48b^4
3(a^4-16b^4) (taking 3 as common)
