expand (4x^2-1)/((x+2)^2)

expand

\frac{4 x ^{2} - 1}{( x + 2 ) ^{2}}

\frac{4 x ^{2} - 1}{x ^{2} + 4 x + 4}

Solution steps

\frac{4 x ^{2} - 1}{( x + 2 ) ^{2}}

(x + 2)^{2} = x^{2} + 4 x + 4

= \frac{4 x ^{2} - 1}{x ^{2} + 4 x + 4}

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

- \frac{p}{( p + 1 ) ( p + 2 )}

20000 (x - 4) e^{- \frac{x}{2} - 1}

(x - 2 y) d x + (2 x + y) d y

(4 + i)^{4}
