desarrollar 16x-(x^2(pi+4))/8

Solución

desarrollar

16 x - \frac{x ^{2} ( π + 4 )}{8}

Solución

16 x - \frac{π x ^{2}}{8} - \frac{x ^{2}}{2}

Pasos de solución

16 x - \frac{x ^{2} ( π + 4 )}{8}

Expandir

x^{2} (π + 4) : π x^{2} + 4 x^{2}

= 16 x - \frac{π x ^{2} + 4 x ^{2}}{8}

Aplicar las propiedades de las fracciones:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{π x ^{2} + 4 x ^{2}}{8} = - (\frac{π x ^{2}}{8}) - (\frac{4 x ^{2}}{8})

= 16 x - (\frac{π x ^{2}}{8}) - (\frac{4 x ^{2}}{8})

Quitar los parentesis:

(a) = a

= 16 x - \frac{π x ^{2}}{8} - \frac{4 x ^{2}}{8}

Cancelar

\frac{4 x ^{2}}{8} : \frac{x ^{2}}{2}

= 16 x - \frac{π x ^{2}}{8} - \frac{x ^{2}}{2}
