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

expand

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

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

Solution steps

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

Expand

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

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

- 5 (1 - 5 x) + 5 (- 8 x - 2 = - 4 x - 8 x)

A (4, - 3, 1) b (- 2, 4, - 1)

(e^{x} + 1) (e^{x} + 2)

\frac{x ( 19 x ^{2} + 12 )}{3}

\frac{x ^{2} - 10 x + 31}{( x - 5 ) ^{2}}
