expand (3x^2-27)/((x-1)(x-9))

expand

\frac{3 x ^{2} - 27}{( x - 1 ) ( x - 9 )}

\frac{3 x ^{2} - 27}{x ^{2} - 10 x + 9}

Solution steps

\frac{3 x ^{2} - 27}{( x - 1 ) ( x - 9 )}

Expand

(x - 1) (x - 9) : x^{2} - 10 x + 9

= \frac{3 x ^{2} - 27}{x ^{2} - 10 x + 9}

\frac{2 x}{( x ^{2} + 3 ) ^{2}}

\frac{( x + 3 ) ^{2}}{x - 4}

\frac{5 ( 132101 - 61 )}{49}

\frac{x ( ( x - 3 ) ^{2} )}{9}

(1 - e^{- 3 x})^{2}
