Solution for 2x(x+7y)-3y(x-4y)-11xy= equation:


Simplifying
2x(x + 7y) + -3y(x + -4y) + -11xy = 0
(x * 2x + 7y * 2x) + -3y(x + -4y) + -11xy = 0

Reorder the terms:
(14xy + 2x2) + -3y(x + -4y) + -11xy = 0
(14xy + 2x2) + -3y(x + -4y) + -11xy = 0
14xy + 2x2 + (x * -3y + -4y * -3y) + -11xy = 0
14xy + 2x2 + (-3xy + 12y2) + -11xy = 0

Reorder the terms:
14xy + -3xy + -11xy + 2x2 + 12y2 = 0

Combine like terms: 14xy + -3xy = 11xy
11xy + -11xy + 2x2 + 12y2 = 0

Combine like terms: 11xy + -11xy = 0
0 + 2x2 + 12y2 = 0
