Exercise
$\left(a^4-2\right)\left(a^8+2a^4+4\right)$
Step-by-step Solution
Learn how to solve special products problems step by step online. Expand the expression (a^4-2)(a^8+2a^4+4). Multiply the single term a^8+2a^4+4 by each term of the polynomial \left(a^4-2\right). Multiply the single term a^4 by each term of the polynomial \left(a^8+2a^4+4\right). When multiplying exponents with same base we can add the exponents. When multiplying two powers that have the same base (a^4), you can add the exponents.
Expand the expression (a^4-2)(a^8+2a^4+4)
Final answer to the exercise
$a^{12}-8$
