Exercise
$\left(2y^3-6y^2-6y+7\right)\cdot\left(9y-2\right)$
Step-by-step Solution
Learn how to solve problems step by step online. Expand the expression (2y^3-6y^2-6y+7)(9y-2). Multiply the single term 9y-2 by each term of the polynomial \left(2y^3-6y^2-6y+7\right). Multiply the single term 2y^3 by each term of the polynomial \left(9y-2\right). When multiplying exponents with same base you can add the exponents: 18y\cdot y^3. Multiply the single term -6y^2 by each term of the polynomial \left(9y-2\right).
Expand the expression (2y^3-6y^2-6y+7)(9y-2)
Final answer to the exercise
$18y^{4}-58y^{3}-42y^2+75y-14$
