expand 1+(xsqrt(x^2+2))^2

expand

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

x^{4} + 2 x^{2} + 1

Solution steps

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

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

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

Expand

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

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

Rewrite in standard form

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

(\frac{d ^{2}}{4 r ^{2}} - \frac{d cos ( θ )}{r})^{3}

(5 - 2 a)^{2}

\frac{2 ( 5 t ^{3} + C )}{7}

10 (3 - 1)

2 (4 + 32)
