Exercise
$x\left(x+1\right)\left(x^2+12x-84\right)$
Step-by-step Solution
Learn how to solve problems step by step online. Expand the expression x(x+1)(x^2+12x+-84). Multiply the single term x\left(x^2+12x-84\right) by each term of the polynomial \left(x+1\right). When multiplying two powers that have the same base (x), you can add the exponents. Multiply the single term x^2 by each term of the polynomial \left(x^2+12x-84\right). When multiplying exponents with same base we can add the exponents.
Expand the expression x(x+1)(x^2+12x+-84)
Final answer to the exercise
$x^{4}+13x^{3}-72x^2-84x$
