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 - yy - yz - z x - zy - zz

Simplify

xx + x y + x z - y x - yy - yz - z x - zy - zz : x^{2} - y^{2} - 2 yz - z^{2}

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

\frac{7}{8} + \frac{5}{6}

\frac{7}{6 x} + \frac{1}{6 x ^{2}}

(x - y) \cdot (x + y)

- 9 (1 - 10 n) - 2 (3 n + 9)

(x^{2} + 2 x - 3) (3 x^{2} - 2 x + 4)
