desarrollar ((10-x)^2)/(16)+(x^2)/(4pi)

Solución

expand

\frac{25}{4} - \frac{5 x}{4} + \frac{x ^{2}}{16} + \frac{x ^{2}}{4 π}

Pasos de solución

\frac{( 10 - x ) ^{2}}{16} + \frac{x ^{2}}{4 π}

(10 - x)^{2} = 100 - 20 x + x^{2}

= \frac{x ^{2} - 20 x + 100}{16} + \frac{x ^{2}}{4 π}

Aplicar las propiedades de las fracciones:

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

\frac{100 - 20 x + x ^{2}}{16} = \frac{100}{16} - \frac{20 x}{16} + \frac{x ^{2}}{16}

= \frac{100}{16} - \frac{20 x}{16} + \frac{x ^{2}}{16} + \frac{x ^{2}}{4 π}
