(a + b - c) (a + b + c)

a^{2} + 2 ab + b^{2} - c^{2}

Solution steps

(a + b - c) (a + b + c)

Distribute parentheses

= aa + ab + a c + ba + bb + b c - c a - c b - cc

Simplify

aa + ab + a c + ba + bb + b c - c a - c b - cc : a^{2} + 2 ab + b^{2} - c^{2}

= a^{2} + 2 ab + b^{2} - c^{2}

(2 + 1)^{2}

\frac{20}{35}

\frac{315}{180}

\frac{7 x ^{3}}{14 x ^{2} + 112 x}

\frac{x ^{2} - x - 6}{x ^{2} - 2 x - 3}
