expand (-12x-5y)^2

expand

(- 12 x - 5 y)^{2}

144 x^{2} + 120 x y + 25 y^{2}

Solution steps

(- 12 x - 5 y)^{2}

Apply Perfect Square Formula:

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

(- 12 x - 5 y)^{2} = (- 12 x)^{2} - 2 (- 12 x) \cdot 5 y + (5 y)^{2}

= (- 12 x)^{2} - 2 (- 12 x) \cdot 5 y + (5 y)^{2}

Simplify

(- 12 x)^{2} - 2 (- 12 x) \cdot 5 y + (5 y)^{2} : 144 x^{2} + 120 x y + 25 y^{2}

= 144 x^{2} + 120 x y + 25 y^{2}

0 \times 4

\frac{3}{7 x} + \frac{8}{5 x}

\frac{2}{3} \times \frac{2}{5}

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

\frac{34}{17}
