Question

which are the four identities in factorisation​

Answer 1

Step-by-step explanation:

In this section we will learn Factorization using Identities one by one.

a 2 + 2ab + b 2 = (a + b) 2

a 2 – 2ab + b 2 = (a – b) 2

a 2 – b 2 = (a + b) (a – b)

x 2 + (a + b) x + ab = (x + a) (x + b)

Answer 2

Step-by-step explanation:

a 2 + 2ab + b 2 = (a + b) 2

a 2 – 2ab + b 2 = (a – b) 2

a 2 – b 2 = (a + b) (a – b)

x 2 + (a + b) x + ab = (x + a) (x + b)
