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}

\frac{3 x}{x - 3} + \frac{5}{x ^{2} - 9}

lo g_{327} (+ lo g_{3} (81))

(x - 4) (x - 5) (x + 2) (x + 7)

(3 x + 4) (2 x - 5)

- 1 - 8
