Exercise
$\left(m+n+u\right)\left(m+n-u\right)$
Step-by-step Solution
Learn how to solve problems step by step online. Solve the product (m+nu)(m+n-u). Multiply the single term m+n-u by each term of the polynomial \left(m+n+u\right). Multiply the single term m by each term of the polynomial \left(m+n-u\right). When multiplying two powers that have the same base (m), you can add the exponents. Multiply the single term n by each term of the polynomial \left(m+n-u\right).
Solve the product (m+nu)(m+n-u)
Final answer to the exercise
$m^2+2mn+n^2-u^2$
