Question

2{(a+b) whole square} - 5(a+b)-3

plzz tell me

Answer 1

Step-by-step explanation:

question:

$2 {(a + b)}^{2} - 5(a + b) - 3$

let (a+b) be equal to x

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

$roots \: are =$

$\frac{5 + - \sqrt{25 + 24}}{4}$

$roots \: are = \\ 3 \: and \: - \frac{1}{2}$

so,

(a+b)=3 as well as -1/2
