expand (4x^2+8x-6)/((x+3)^2(x-3))

expand

\frac{4 x ^{2} + 8 x - 6}{( x + 3 ) ^{2} ( x - 3 )}

\frac{4 x ^{2} + 8 x - 6}{x ^{3} + 3 x ^{2} - 9 x - 27}

Solution steps

\frac{4 x ^{2} + 8 x - 6}{( x + 3 ) ^{2} ( x - 3 )}

(x + 3)^{2} = x^{2} + 6 x + 9

= \frac{4 x ^{2} + 8 x - 6}{( x ^{2} + 6 x + 9 ) ( x - 3 )}

Expand

(x^{2} + 6 x + 9) (x - 3) : x^{3} + 3 x^{2} - 9 x - 27

= \frac{4 x ^{2} + 8 x - 6}{x ^{3} + 3 x ^{2} - 9 x - 27}

\frac{1}{cos ^{2} ( x )}

\frac{4}{( u + 1 ) ^{2} ( u ^{2} + 1 )}

\frac{( 2 x ^{2} - x - 6 ) ( 2 x + 3 )}{x - 1}

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

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