Question

Factorize :- 7 + 10(x + y) - 8 (x- y)^2

Answer 1

Hey Dear ^^

I think its (x +y) 

7 + 10(x+y) - 8( x + y)²

Now, 

lets make the equation simple 

say (x+y) = r 

7 + 10r  - 8r²

or 

-8r² + 10r + 7 

-8r² + 14r - 4r + 7 

2r(-4r +7) +1(-4r + 7) 

(-4r+7) ( 2r + 1) 

put r = (x+y ) 

[ -4(x+y) + 7 ] [ 2(x+y) + 1]
