Question

factorise (2a+b)^2+5(2a+b)^2+6​

Answer 1

Answer:

Factorisation of (2a-b)²+2(2a-b)-8

= (2a-b+4)(2a-b-2)

Explanation:

Given (2a-b)²+2(2a-b)-8

To Find:

Factorisation of (2a-b)²+2(2a-b)-8

solution:

Splitting the middle term, we get

= (2a-b)²+4(2a-b)-2(2a-b)-8

= (2a-b)[2a-b+4]-2[2a-b+4]

= (2a-b+4)(2a-b-2)
