$2\left(2a-b\right)^2+\left(a+2b\right)^2-\left(a-2b\right)^2$
Learn how to solve definition of derivative problems step by step online. Reduce like terms (2a-b)^2+(2a-b)^2(a+2b)^2-(a-2b)^2. Combining like terms \left(2a-b\right)^2 and \left(2a-b\right)^2. Expand \left(2a-b\right)^2. The power of a product is equal to the product of it's factors raised to the same power. Multiply the single term 2 by each term of the polynomial \left(4a^2-4ab+b^2\right).
