expand (x^2-4)/(7(x^2-9))

expand

\frac{x ^{2} - 4}{7 ( x ^{2} - 9 )}

\frac{x ^{2} - 4}{7 x ^{2} - 63}

Solution steps

\frac{x ^{2} - 4}{7 ( x ^{2} - 9 )}

Expand

7 (x^{2} - 9) : 7 x^{2} - 63

= \frac{x ^{2} - 4}{7 x ^{2} - 63}

\frac{- 2 x + x h + 2 h}{( x + 2 ) h}

2 + e^{t} (- sin (t) - cos (t))

π (2 - 1)

\frac{73 ( x + 7 y ) ^{2}}{50}

\frac{x}{x ^{2} + x h}
