Exercise
$\left(b-3y\right)\left(b+15y\right)$
Step-by-step Solution
Learn how to solve differential calculus problems step by step online. Solve the product (b-3y)(b+15y). Multiply the single term b+15y by each term of the polynomial \left(b-3y\right). Multiply the single term b by each term of the polynomial \left(b+15y\right). When multiplying two powers that have the same base (b), you can add the exponents. Multiply the single term -3y by each term of the polynomial \left(b+15y\right).
Solve the product (b-3y)(b+15y)
Final answer to the exercise
$b^2+12by-45y^2$
