Question

(2a+b)²+3(2a+b)+2 factorise it ​

Answer 1

Step-by-step explanation:

Let (2a + b) = x

(2a + b)2 = x2

(2a + b)2 + 5(2a + b)  +6

= x2 + 5x + 6

= x2 + 3x + 2x + 6

= x (x + 3) + 2 (x + 3)

= (x + 3) (x + 2)

= (2a + b + 3) (2a + b + 2)

(Substituting the value of x)

Answer 2

$(2a + b + 2)(2a +b +1)$
