Question

Simplify the expression by combining like terms put each expression in its simplest form. 1. 5x^2-2xy+3y^2-4yx+3x-4y^2-5xy+2x-y

Answer 1

5x^2-7xy-2y^2-4yx+3x+2x

Answer 2

5x^2 - 2xy + 3y^2 - 4xy + 3x - 4y^2 - 5xy + 2x - y = 5x^2 - (2xy + 4xy + 5xy) + (3y^2 - 4y^2) + (3x + 2x) - y = 5x^2 - 11xy - y^2 + 5x - y
