$x^{12}+9x^{8}x+3x^{8}+\left(3x\right)^3+3x^4\left(3x\right)^2+3\left(3x\right)^2+1+3x^4+9x+18x^4x$
Learn how to solve special products problems step by step online. Expand the expression (x^4+3x+1)^3. Expand the cube of a trinomial. When multiplying exponents with same base you can add the exponents: 9x^{8}x. When multiplying exponents with same base you can add the exponents: 18x^4x. The power of a product is equal to the product of it's factors raised to the same power.
