\left(2x^{3}+x\right)^{4}a=-1
Persamaan berada dalam bentuk standar.
\frac{\left(2x^{3}+x\right)^{4}a}{\left(2x^{3}+x\right)^{4}}=-\frac{1}{\left(2x^{3}+x\right)^{4}}
Bagi kedua sisi dengan \left(x+2x^{3}\right)^{4}.
a=-\frac{1}{\left(2x^{3}+x\right)^{4}}
Membagi dengan \left(x+2x^{3}\right)^{4} membatalkan perkalian dengan \left(x+2x^{3}\right)^{4}.
a=-\frac{1}{\left(x\left(2x^{2}+1\right)\right)^{4}}
Bagi -1 dengan \left(x+2x^{3}\right)^{4}.
