Answer:
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

The range of the function f(x) = 3x^2 + 6x - 8 is <span>{y|y ≥ –11}</span>
Answer & Step-by-step explanation:
For a polynomial of the form 
+bx+c
, rewrite the middle term as a sum of two terms whose product is a×c=6×−12=−72 and whose sum is b=−1.
Factor −1 out of −x.
−(x)−12
Rewrite −1 as −9 plus 8
+(−9+8)x−12
Apply the distributive property.
−9x+8x−12
Factor out the greatest common factor from each group.
Group the first two terms and the last two terms.
(-9x)+8x−12
Factor out the greatest common factor (GCF) from each group.
