$2m\left(m-n\right)+\left(-m-n\right)\left(m-n\right)$
Learn how to solve special products problems step by step online. Expand the expression 2m(m-n)-(m+n)(m-n). Simplify the product -(m+n). Multiply the single term 2m by each term of the polynomial \left(m-n\right). When multiplying two powers that have the same base (m), you can add the exponents. Multiply the single term m-n by each term of the polynomial \left(-m-n\right).
