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]
I think its (x +y)
7 + 10(x+y) - 8( x + y)²

(-4r+7) ( 2r + 1)
put r = (x+y )
[ -4(x+y) + 7 ] [ 2(x+y) + 1]
MakutoShiedo:
It's (x - y)
But i think it should be (x+y)
ok.....can it be solved with (x - y)
Mere hisab se to nhi hoga sis
