expand (x+y+3)(x+y-2)

expand

(x + y + 3) (x + y - 2)

x^{2} + 2 x y + x + y^{2} + y - 6

Solution steps

(x + y + 3) (x + y - 2)

Distribute parentheses

= xx + x y + x (- 2) + y x + yy + y (- 2) + 3 x + 3 y + 3 (- 2)

Simplify

xx + x y + x (- 2) + y x + yy + y (- 2) + 3 x + 3 y + 3 (- 2) : x^{2} + 2 x y + x + y^{2} + y - 6

= x^{2} + 2 x y + x + y^{2} + y - 6

5 x^{2} - 25 x

(2 x^{3} + 5 x)^{2}

(4 + x - 2) (4 + x + 2)

- 2 y^{3} - y^{2} + y^{2} + y^{3}

x^{2} + 50 x + 336
