expand (x+y+z)(x+y-z)

expand

(x + y + z) (x + y - z)

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

Solution steps

(x + y + z) (x + y - z)

Distribute parentheses

= xx + x y + x (- z) + y x + yy + y (- z) + z x + zy + z (- z)

Simplify

xx + x y + x (- z) + y x + yy + y (- z) + z x + zy + z (- z) : x^{2} + 2 x y + y^{2} - z^{2}

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

- 3 (1 - 5 x)

(1 - 5 q) + 2 (2.5 q + 8)

(5 x + 6)^{2}

\frac{27}{9}

(- 4 + 3 i) (- 12 + 6 i)
