Exercise
$\left(3x^2-x\right)\left(5x+4\right)$
Step-by-step Solution
Learn how to solve special products problems step by step online. Expand the expression (3x^2-x)(5x+4). Multiply the single term 5x+4 by each term of the polynomial \left(3x^2-x\right). Multiply the single term 3x^2 by each term of the polynomial \left(5x+4\right). When multiplying exponents with same base you can add the exponents: 15x\cdot x^2. Multiply the single term -x by each term of the polynomial \left(5x+4\right).
Expand the expression (3x^2-x)(5x+4)
Final answer to the exercise
$15x^{3}+7x^2-4x$
