Question

please answer it as fast as possible​

Answer 1

(a+b)² + 9(a+b) + 14

let (a+b) = x

then,

⇒x²+9x+14

⇒x²+7x+2x+14

⇒x(x+7)+2(x+7)

⇒(x+7)(x+2)

⇒[(a+b)+7] [(a+b)+2]

⇒(a+b+7)(a+b+2)

Answer 2

Answer:

this can help you

Step-by-step explanation:

(a+b)2+9(a+b)+14

let a+b=X

X2+9x+14

X2+7x+2x+14

X(X+7)+2(X+7)

(X+7)(x+2)

{(a+b)+7}{(a+b)+2}

(a+b+7)(a+b+2)
