Answer 2

Required Answer:-

Given to factorise:

• (5x - 1)(x + 1) + (x + 1)

Solution:

This is a very simple factorisation. We will take (x + 1) as common factor and then we will factorise it.

Here is the solution.

(5x - 1)(x + 1) + (x + 1)

= (5x - 1)(x + 1) + 1(x + 1)

= (x + 1)[ (5x - 1) + 1 ]

= (x + 1)(5x)

= 5x(x + 1)

Hence, the factorised form is 5x(x + 1)

Answer:

• The factorised form is 5x(x + 1)
