Step-by-step Solution
Learn how to solve special products problems step by step online. \left(- a - b + 2x - y\right) \left(a + b + 2x - y\right) . Math interpretation of the question. 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.. The power of a product is equal to the product of it's factors raised to the same power. Expand the trinomial using the formula \left(a+b+c\right)^2 = a^2 + b^2 + c^2 + 2ab + 2ac + 2bc.
\left(- a - b + 2x - y\right) \left(a + b + 2x - y\right)
Final answer to the exercise
$4x^2-a^2-b^2-y^2-2ab+2ay+2by$
