espandere (4(2xz^pi-yt)(2xz^pi+yt))/(y^2z^{2pi)}

Soluzione

espandere

\frac{4 ( 2 x z ^{π} - y t ) ( 2 x z ^{π} + y t )}{y ^{2} z ^{2 π}}

\frac{16 x ^{2}}{y ^{2}} - \frac{4 t ^{2}}{z ^{2 π}}

Fasi della soluzione

\frac{4 ( 2 x z ^{π} - y t ) ( 2 x z ^{π} + y t )}{y ^{2} z ^{2 π}}

Espandi

4 (2 x z^{π} - y t) (2 x z^{π} + y t) : 16 x^{2} z^{2 π} - 4 y^{2} t^{2}

= \frac{16 x ^{2} z ^{2 π} - 4 y ^{2} t ^{2}}{y ^{2} z ^{2 π}}

Applica la regola delle frazioni:

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

\frac{16 x ^{2} z ^{2 π} - 4 y ^{2} t ^{2}}{y ^{2} z ^{2 π}} = \frac{16 x ^{2} z ^{2 π}}{y ^{2} z ^{2 π}} - \frac{4 y ^{2} t ^{2}}{y ^{2} z ^{2 π}}

= \frac{16 x ^{2} z ^{2 π}}{y ^{2} z ^{2 π}} - \frac{4 y ^{2} t ^{2}}{y ^{2} z ^{2 π}}

Cancellare

\frac{16 x ^{2} z ^{2 π}}{y ^{2} z ^{2 π}} : \frac{16 x ^{2}}{y ^{2}}

= \frac{16 x ^{2}}{y ^{2}} - \frac{4 y ^{2} t ^{2}}{y ^{2} z ^{2 π}}

Cancellare

\frac{4 y ^{2} t ^{2}}{y ^{2} z ^{2 π}} : \frac{4 t ^{2}}{z ^{2 π}}

= \frac{16 x ^{2}}{y ^{2}} - \frac{4 t ^{2}}{z ^{2 π}}
