Exercise
$\left(x^{4}+6x^{3}-4x^{-2}-7x\right)\left(4x^{3}+6x^{2}-8x\right)$
Step-by-step Solution
Learn how to solve polynomial long division problems step by step online. Expand the expression (x^4+6x^3-4x^(-2)-7x)(4x^3+6x^2-8x). Multiply the single term 4x^3+6x^2-8x by each term of the polynomial \left(x^4+6x^3-4x^{-2}-7x\right). Multiply the single term x^4 by each term of the polynomial \left(4x^3+6x^2-8x\right). When multiplying exponents with same base we can add the exponents. When multiplying exponents with same base you can add the exponents: -8x\cdot x^4.
