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

expand

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

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

Solution steps

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

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

Apply the distributive law:

a (b + c) = ab + a c

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

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

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

\frac{( ( 1 - x ) ^{3} )}{3}

(e^{18 x} + e^{- 18 x})^{2}

5 + i (- 3 + 26)

- (e^{i x} + e^{- i x}) i (e^{i x} - e^{- i x})

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