expand (-p+r)/((q-r)^2)

expand

\frac{- p + r}{( q - r ) ^{2}}

\frac{- p + r}{q ^{2} - 2 r q + r ^{2}}

Solution steps

\frac{- p + r}{( q - r ) ^{2}}

(q - r)^{2} = q^{2} - 2 r q + r^{2}

= \frac{- p + r}{q ^{2} - 2 r q + r ^{2}}

(a + b + c + d + e + f + g)^{2}

\frac{( - x + 6 ) ( - 3 x - 28 )}{3}

\frac{2 s ^{4} - s ^{3} + 12 s - 12}{s ^{4} ( s - 1 )}

e^{x} \cdot (e^{x} + e^{x} x)

(e^{- 2 x} (2 - x) + x)^{2}
