Exercise
$6x^{a+b}\left(7x^a+5x^b+x^{2a+b}-4\right)$
Step-by-step Solution
Learn how to solve problems step by step online. Expand the expression 6x^(a+b)(7x^a+5x^bx^(2a+b)+-4). Multiply the single term 6x^{\left(a+b\right)} by each term of the polynomial \left(7x^a+5x^b+x^{\left(2a+b\right)}-4\right). When multiplying exponents with same base we can add the exponents. When multiplying exponents with same base we can add the exponents. When multiplying exponents with same base we can add the exponents.
Expand the expression 6x^(a+b)(7x^a+5x^bx^(2a+b)+-4)
Final answer to the exercise
$42x^{\left(2a+b\right)}+30x^{\left(2b+a\right)}+6x^{\left(3a+2b\right)}-24x^{\left(a+b\right)}$
