ln (x) (x^{2} - 1)

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

Pasos de solución

ln (x) (x^{2} - 1)

Poner los parentesis utilizando:

a (b - c) = ab - a c

a = ln (x), b = x^{2}, c = 1

= ln (x) x^{2} - ln (x) \cdot 1

= x^{2} ln (x) - 1 \cdot ln (x)

Multiplicar:

1 \cdot ln (x) = ln (x)

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

(2 + 3 x - 4 x^{2})^{5}

- 8 d + (- 1) + 9 d^{2} + 8 d

\frac{2 x}{x}

2 (d + f^{2} - e^{2})^{2}

\frac{a ^{2}}{( x + a ) ^{2} \cdot x}
