Exercise
$\left(x+8\right)^2\left(x-5\right)^2\:-\left(x+2\right)^2\left(x+1\right)^2\:+84x\left(x+3\right)$
Step-by-step Solution
Learn how to solve problems step by step online. Expand the expression (x+8)^2(x-5)^2-(x+2)^2(x+1)^284x(x+3). Multiply the single term 84x by each term of the polynomial \left(x+3\right). When multiplying two powers that have the same base (x), you can add the exponents. Expand \left(x-5\right)^2. Expand the expression \left(x+8\right)^2 using the square of a binomial.
Expand the expression (x+8)^2(x-5)^2-(x+2)^2(x+1)^284x(x+3)
