Exercise
$x^4-\left(x+4\right)\left(x-4\right)\left(x^2+19\right)$
Step-by-step Solution
Learn how to solve special products problems step by step online. Expand the expression x^4-(x+4)(x-4)(x^2+19). The sum of two terms multiplied by their difference is equal to the square of the first term minus the square of the second term. In other words: (a+b)(a-b)=a^2-b^2.. Simplify the product -(x^2-16). Multiply the single term x^2+19 by each term of the polynomial \left(-x^2+16\right). Multiply the single term -x^2 by each term of the polynomial \left(x^2+19\right).
Expand the expression x^4-(x+4)(x-4)(x^2+19)
Final answer to the exercise
$-3x^2+304$
