x_{1}x^{2}+x^{3}-x^{9}+6=9^{3x}+2
To multiply powers of the same base, add their exponents. Add 4 and 5 to get 9.
x_{1}x^{2}-x^{9}+6=9^{3x}+2-x^{3}
Subtract x^{3} from both sides.
x_{1}x^{2}+6=9^{3x}+2-x^{3}+x^{9}
Add x^{9} to both sides.
x_{1}x^{2}=9^{3x}+2-x^{3}+x^{9}-6
Subtract 6 from both sides.
x_{1}x^{2}=9^{3x}-4-x^{3}+x^{9}
Subtract 6 from 2 to get -4.
x^{2}x_{1}=x^{9}-x^{3}+729^{x}-4
The equation is in standard form.
\frac{x^{2}x_{1}}{x^{2}}=\frac{x^{9}-x^{3}+729^{x}-4}{x^{2}}
Divide both sides by x^{2}.
x_{1}=\frac{x^{9}-x^{3}+729^{x}-4}{x^{2}}
Dividing by x^{2} undoes the multiplication by x^{2}.
