$9 x^{4} a^{2} + 15 x^{2} a^{3} = 3 x^{2} a^{2}$

Step 1

Subtract $3 x^{2} a^{2}$ from both sides of the equation.

$9 x^{4} a^{2} + 15 x^{2} a^{3} - 3 x^{2} a^{2} = 0$

Step 2

The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.
