Exercise
$\left(x+5\right)^2-\left(2x-3\right)^2+2\left(x+4\right)\left(x-4\right)$
Step-by-step Solution
Learn how to solve special products problems step by step online. Expand the expression (x+5)^2-(2x-3)^22(x+4)(x-4). 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.. Multiply the single term 2 by each term of the polynomial \left(x^2-16\right). Expand \left(2x-3\right)^2. The power of a product is equal to the product of it's factors raised to the same power.
Expand the expression (x+5)^2-(2x-3)^22(x+4)(x-4)
Final answer to the exercise
$-x^2+22x-16$
