expand (2x^2-14x+21)/((x-3)^2)

expand

\frac{2 x ^{2} - 14 x + 21}{( x - 3 ) ^{2}}

\frac{2 x ^{2} - 14 x + 21}{x ^{2} - 6 x + 9}

Solution steps

\frac{2 x ^{2} - 14 x + 21}{( x - 3 ) ^{2}}

(x - 3)^{2} = x^{2} - 6 x + 9

= \frac{2 x ^{2} - 14 x + 21}{x ^{2} - 6 x + 9}

\frac{2 z ( z + 4 )}{z - 1}

\frac{( ( x - 1 ) ( x + 1 ) )}{( 3 - 2 x )}

\frac{0.00034 ( 1 + 7.5 s )}{( 1 + 2 s )}

\frac{d}{d x} ((7 x^{2} - 9 x) (5 x + 8)) - 1

\frac{- s ^{2} + e ^{- 5 s} + e ^{5 s} + 2}{s ^{2} ( s ^{2} + s - 2 )}
