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

expand

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

\frac{9 x - 4}{x ^{2} - 4}

Solution steps

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

Expand

(x + 2) (x - 2) : x^{2} - 4

= \frac{9 x - 4}{x ^{2} - 4}

(y - 3 t y - t^{2}) d t + t^{2} d y

\frac{11 ( x + h ) ^{2} - 3 ( x + h )}{h}

(b + c) (d - e)

1 + csc (θ) (1 - sin (θ) = cot (θ) \cdot cos (θ))

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