expand 9(x+dx)^3

expand

9 (x + d x)^{3}

9 x^{3} + 27 x^{2} d x + 27 x d x^{2} + 9 d x^{3}

Solution steps

9 (x + d x)^{3}

(x + d x)^{3} = x^{3} + 3 x^{2} d x + 3 x d x^{2} + d x^{3}

= 9 (x^{3} + 3 x^{2} d x + 3 x d x^{2} + d x^{3})

Distribute parentheses

= 9 x^{3} + 9 \cdot 3 x^{2} d x + 9 \cdot 3 x d x^{2} + 9 d x^{3}

Multiply the numbers:

9 \cdot 3 = 27

= 9 x^{3} + 27 x^{2} d x + 27 x d x^{2} + 9 d x^{3}

\frac{1}{3} (2 x - e^{x})

- 2 (9 e^{x} + x e^{x})

C (- 1, 3) v (4, - 3) F (2, - 3)

\frac{3 ( k + 2 ) ( k - 3 )}{5}

(t - e^{2 t}) \cdot (- (3 + 2 e^{2 t}))
