Answer 2

The given question is solved in the uploaded photo.

Factorising an expression means to find the factors of that expression ,that is the exact divisors of the expression.

It can be done in any of the following ways -

1) By taking common terms

2) By using identities

3) By using middle term factorisation.

Additional information-

Some of the factorising identities are listed below-

$1) \: {a}^{2} + 2ab + {b}^{2} = {(a + b)}^{2} \\ 2) {a}^{2} - 2ab + b ^{2} = {(a - b)}^{2} \\ 3) {a }^{2} - {b}^{2} = (a + b)(a - b) \\ 4) {a}^{3} + {b}^{3} + 3 {a}^{2}b + 3a {b }^{2} \\ = {(a + b)}^{3} \\ 5) {a}^{3} - {b}^{3} - 3 {a}^{2} b + 3a {b}^{2} \\ = {(a - b)}^{3}$
