Question

simplify : ( 3x^2 + 2xy - 1) - ( x^2 - 5x - y^2 + 6 ) HELPPPPPPPP....

Answer 1

group it:
(3x^2 -x^2)+2xy -(1+6) +5x+y^2=...
can you take it from here?

Answer 2

NO

Answer 3

ok.
let's try together...
2x^2 +2xy -7 +5x+y^2=(x+y)^2 +(x^2+5x-7)
agreed so far?

Answer 4

YES

Answer 5

i'm not sure what grade you are in... what exactly you expected to do when "simplify"...?
leave all as:
2x^2 +y^2+2xy +5x-7
or something else?

Answer 6

:)

Answer 7

ok
