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

expand

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

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

Solution steps

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

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

Apply the distributive law:

a (b + c) = ab + a c

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

= x^{2} + 1 x^{2} + x^{2} + 1 \cdot 1

Simplify

x^{2} + 1 x^{2} + x^{2} + 1 \cdot 1 : x^{2} x^{2} + 1 + x^{2} + 1

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

(c - d)^{2}

m + n + r - 2 (m + n) r

\frac{x ^{9} y}{( x ^{6} + y ^{2} ) ^{2}}

2 (4 + 25)

(r^{2} - 2 r) e^{r}
