Exercise
$\left(a+b\right)\left(2a-4b+1\right)$
Step-by-step Solution
Learn how to solve special products problems step by step online. Expand the expression (a+b)(2a-4b+1). Multiply the single term 2a-4b+1 by each term of the polynomial \left(a+b\right). Multiply the single term a by each term of the polynomial \left(2a-4b+1\right). When multiplying two powers that have the same base (a), you can add the exponents. Multiply the single term b by each term of the polynomial \left(2a-4b+1\right).
Expand the expression (a+b)(2a-4b+1)
Final answer to the exercise
$2a^2-2ab+a-4b^2+b$
