Exercise
$\left(2x-y\right)\left(x^2-15x+5\right)-3x\left(x+4\right)\:$
Step-by-step Solution
Learn how to solve problems step by step online. Expand the expression (2x-y)(x^2-15x+5)-3x(x+4). Multiply the single term x^2-15x+5 by each term of the polynomial \left(2x-y\right). Multiply the single term 2x by each term of the polynomial \left(x^2-15x+5\right). When multiplying exponents with same base you can add the exponents: 2x^2x. When multiplying two powers that have the same base (x), you can add the exponents.
Expand the expression (2x-y)(x^2-15x+5)-3x(x+4)
Final answer to the exercise
$2x^{3}-33x^2-2x-x^2y+15xy-5y$
