Exercise
$\left(x^2-1\right)\left(x+1\right)\left(x^2+7\right)$
Step-by-step Solution
Learn how to solve special products problems step by step online. Expand the expression (x^2-1)(x+1)(x^2+7). Multiply the single term \left(x+1\right)\left(x^2+7\right) by each term of the polynomial \left(x^2-1\right). Multiply the single term x^2\left(x^2+7\right) by each term of the polynomial \left(x+1\right). When multiplying exponents with same base you can add the exponents: x\cdot x^2\left(x^2+7\right). Multiply the single term x^{3} by each term of the polynomial \left(x^2+7\right).
Expand the expression (x^2-1)(x+1)(x^2+7)
Final answer to the exercise
$x^{5}+6x^{3}+x^{4}+6x^2-7x-7$
