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

expand

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

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

Solution steps

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

Distribute parentheses

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

Simplify

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

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

- \frac{3}{- 2}

(a + x) (a - x)

y^{'} (x) + (\frac{4}{x}) y - (x^{3}) (y^{2})

(8 - i) - (10 - 8 i)
