Question

Factorise: x² - ysquare + ax + ay.​

Answer 1

Step-by-step explanation:

x^2-y^2+ax+ay

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

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

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

Answer 2

Answer:

$= (x-y)×(x-y+a)$

Step-by-step explanation:

$= x²-xy²+ax+ay$

Using a²-b² = (a-b)(a+b)

$= (x-y) × (x+y) + ax+ay$

$= (x-y) (x+y)+ a × (x+y)$

$→ (x-y) × (x-y+a)$
