expand-3x(3x+2xln(x))

expand

- 3 x (3 x + 2 x ln (x))

- 9 x^{2} - 6 x^{2} ln (x)

Solution steps

- 3 x (3 x + 2 x ln (x))

Apply the distributive law:

a (b + c) = ab + a c

a = - 3 x, b = 3 x, c = 2 x ln (x)

= - 3 x \cdot 3 x + (- 3 x) \cdot 2 x ln (x)

Apply minus-plus rules

+ (- a) = - a

= - 3 \cdot 3 xx - 3 \cdot 2 xx ln (x)

Simplify

- 3 \cdot 3 xx - 3 \cdot 2 xx ln (x) : - 9 x^{2} - 6 x^{2} ln (x)

= - 9 x^{2} - 6 x^{2} ln (x)

(\frac{x}{4 y ^{'} ( x )} + y)^{2}

p u n t os (2, - 1) y (\frac{1 , - 9}{7})

\frac{1}{90} (e^{8 x} + 8 e^{8 x} x)

(e^{i θ} + e^{- i θ})^{2}

\frac{x + 2}{2 ( x - 1 )}
