Question

factorization of (x+y)²+9(x+y)+8 is​

Answer 1

Answer:

By middle term factorisation:

(x+y)² +9(x+y)+8

let (x+y) be a.

a² + 9a + 8

a² + 8a + a + 8

a(a+8)+1(a+8)

(a+8)(a+1)

(x+y+8)(x+y+1)

Hopes it helps!

Answer 2

Step-by-step explanation:

2(x + y)² - 9( x + y ) -5 = 0

⇒2(x + y)² - 10 (x+y) +1(x+y) -5 = 0

⇒2(x+y)(x + y - 5 ) + 1(x + y -5 ) = 0

taking (x + y -5 ) common ,

⇒(x + y -5 )[2(x + y) + 1] =0

⇒(x + y -5)(2x + 2y +1) =0
