Exercise
$-4m\left(n-m\right)+4m^2\left(n-m\right)^2$
Step-by-step Solution
Learn how to solve polynomial long division problems step by step online. Expand the expression -4m(n-m)+4m^2(n-m)^2. Multiply the single term -4m by each term of the polynomial \left(n-m\right). When multiplying two powers that have the same base (m), you can add the exponents. Expand \left(n-m\right)^2. Multiply the single term 4m^2 by each term of the polynomial \left(n^2-2nm+m^2\right).
Expand the expression -4m(n-m)+4m^2(n-m)^2
Final answer to the exercise
$-4nm+4m^2+4n^2m^2-8nm^{3}+4m^{4}$
