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 + yz - z x - zy - zz

Simplify

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

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

\frac{tan ( x )}{cos ( x )}

\frac{2}{3} + \frac{5}{3} - \frac{1}{6}

\frac{2}{2 x + 1} + \frac{1}{x + 2}

(\frac{- 5}{10})^{- 2}

\frac{2 x ^{4} + 3 x ^{3} - 2 x ^{2} + 13 x - 24}{x + 3}
