expand ((1+2x^3)^2)/7

Solution

expand

\frac{( 1 + 2 x ^{3} ) ^{2}}{7}

Solution

\frac{4 x ^{6}}{7} + \frac{4 x ^{3}}{7} + \frac{1}{7}

Solution steps

\frac{( 1 + 2 x ^{3} ) ^{2}}{7}

(1 + 2 x^{3})^{2} = 1 + 4 x^{3} + 4 x^{6}

= \frac{1 + 4 x ^{3} + 4 x ^{6}}{7}

Apply the fraction rule:

\frac{a \pm b}{c} = \frac{a}{c} \pm \frac{b}{c}

\frac{1 + 4 x ^{3} + 4 x ^{6}}{7} = \frac{1}{7} + \frac{4 x ^{3}}{7} + \frac{4 x ^{6}}{7}

= \frac{1}{7} + \frac{4 x ^{3}}{7} + \frac{4 x ^{6}}{7}

Rewrite in standard form

= \frac{4 x ^{6}}{7} + \frac{4 x ^{3}}{7} + \frac{1}{7}
