Question

factorise:2(a + b)^2 - 5(a + b) - 3​

Answer 1

Answer:

2(a)^+(b)^+2ab

37997667*7*7

Answer 2

Step-by-step explanation:

Let ( a + b ) = x

$2 {x}^{2} - 5x - 3$

$= 2 {x}^{2} - 6x + x - 3$

$= 2x(x - 3) + 1(x - 3)$

$= (x - 3)(2x + 1)$

Now put the value of x as ( a + b )

$(a + b - 3)(2a + 2b + 1)$

Hence, factorised.
