Question

Please Factorise this

Answer 1

Answer: (a-b+3)(a-b+5) is the answer.

Step-by-step explanation:

Hi! We can factorise by using the identity (x + a)(x + b)=x²+x(a+b)+ab taking two numbers such that a+b=ab

here, x² will be (a-b)²

here, we can see that 3×5 is 15 and 3+5 is 8

so,

(a-b)² + (a-b)(3+5) + 3×5

⇒ (a-b+3)(a-b+5)
