Question

How do you solve this

Answer 1

Start off with exponents

Answer 2

What are you trying to do? Solve for x? If so, normally you'd combine like terms. So, if you had $3x^2+4x^2+5x^3$ you could combine $3x^2$ & $4x^2$ only because they have the same exponent. You'd get $7x^2$, plus the $5x^3$. The end equation would be $5x^3+7x^2$. In your equation, you have no like exponents. Your equation is as simple as it can get.
