Exercise
$\left(3x+4\right)\left(7x^2+6x+2\right)$
Step-by-step Solution
Learn how to solve special products problems step by step online. Expand the expression (3x+4)(7x^2+6x+2). Multiply the single term 7x^2+6x+2 by each term of the polynomial \left(3x+4\right). Multiply the single term 3x by each term of the polynomial \left(7x^2+6x+2\right). When multiplying exponents with same base you can add the exponents: 21x^2x. When multiplying two powers that have the same base (x), you can add the exponents.
Expand the expression (3x+4)(7x^2+6x+2)
Final answer to the exercise
$21x^{3}+46x^2+30x+8$
