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

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

14 x^{2} - 21 x^{3} + 49 x^{4}

5 - (- 10)

\frac{2 - \frac{4}{x + 2}}{5 + \frac{10}{x + 2}}

\frac{3}{4} + \frac{- 2}{5} + \frac{- 7}{10}

\frac{\frac{1}{2} ( cos ^{2} ( x ) - 1 )}{sin ( x ) tan ( x )}
