expand (4x^3-x^2+4x+2)/((2x^2+1)^2)

expand

\frac{4 x ^{3} - x ^{2} + 4 x + 2}{( 2 x ^{2} + 1 ) ^{2}}

\frac{4 x ^{3} - x ^{2} + 4 x + 2}{4 x ^{4} + 4 x ^{2} + 1}

Solution steps

\frac{4 x ^{3} - x ^{2} + 4 x + 2}{( 2 x ^{2} + 1 ) ^{2}}

(2 x^{2} + 1)^{2} = 4 x^{4} + 4 x^{2} + 1

= \frac{4 x ^{3} - x ^{2} + 4 x + 2}{4 x ^{4} + 4 x ^{2} + 1}

(5 x + 6 i)^{2}

(- 6, 4) y (5, - 2)
