expand (-12v+7z)^2

expand

(- 12 v + 7 z)^{2}

144 v^{2} - 168 v z + 49 z^{2}

Solution steps

(- 12 v + 7 z)^{2}

Apply Perfect Square Formula:

(a + b)^{2} = a^{2} + 2 ab + b^{2}

(- 12 v + 7 z)^{2} = (- 12 v)^{2} + 2 (- 12 v) \cdot 7 z + (7 z)^{2}

= (- 12 v)^{2} + 2 (- 12 v) \cdot 7 z + (7 z)^{2}

Simplify

(- 12 v)^{2} + 2 (- 12 v) \cdot 7 z + (7 z)^{2} : 144 v^{2} - 168 v z + 49 z^{2}

= 144 v^{2} - 168 v z + 49 z^{2}

\frac{144}{25}

\frac{x}{x ^{2} - 16} - \frac{3}{x - 4}

(- 1 + 3 i)^{2}

(- 1 + 3 i)^{3}
