expand x^2*(sqrt(x^2+9)+3)

expand

x^{2} \cdot (x^{2} + 9 + 3)

x^{2} x^{2} + 9 + 3 x^{2}

Solution steps

x^{2} (x^{2} + 9 + 3)

Apply the distributive law:

a (b + c) = ab + a c

x^{2} (x^{2} + 9 + 3) = x^{2} x^{2} + 9 + x^{2} \cdot 3

= x^{2} x^{2} + 9 + x^{2} \cdot 3

= x^{2} x^{2} + 9 + 3 x^{2}

x (\frac{x ^{2}}{24} - x + 6) (\frac{32}{3} - \frac{8 x}{9})

(2 - 2 x - 3)^{2}

\frac{( 3 ( k + 1 ) ) ! 2. 3 ^{k + 1}}{( ( k + 1 ) ! ) ^{3}}

l {(x - sin (x))^{2}}

(2 x - 5) ln (2)
