simplify-3(-2y)^3-6(-2y)+9

simplify

- 3 (- 2 y)^{3} - 6 (- 2 y) + 9

24 y^{3} + 12 y + 9

Solution steps

- 3 (- 2 y)^{3} - 6 (- 2 y) + 9

- 3 (- 2 y)^{3} = 24 y^{3}

6 (- 2 y) = - 12 y

= 24 y^{3} - (- 12 y) + 9

Apply rule:

a - (- b) = a + b

24 y^{3} - (- 12 y) = 24 y^{3} + 12 y

= 24 y^{3} + 12 y + 9

1 - \frac{1}{1 + x}

2^{- 1}

125 + g^{3}

(- \frac{2}{9}) (\frac{8}{11})

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