expand (2x^2+x-9)/((x-3)(x+3))

expand

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

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

Solution steps

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

Expand

(x - 3) (x + 3) : x^{2} - 9

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

[(x + Δ x)^{2} + 7]

(4 x - 2 y = 2, 3) (- x + 3 y = 4)

\frac{d ( 2 x + 5 )}{x + 3}

25 (z - 1) (z - e^{- 5 T})

\frac{d}{d x} ((t) (t - 2) e^{t})
