# How do you simplify 5x^3+ 5(6x^3 - 5b^4)?

May 10, 2018

#### Answer:

$5 \left(7 {x}^{3} - 5 {b}^{4}\right)$

#### Explanation:

Let's start by distributing the $5$ to both terms in the parenthesis. Doing this, we get

$5 {x}^{3} + 30 {x}^{3} - 25 {b}^{4}$

We can simplify the ${x}^{3}$ terms to get

$35 {x}^{3} - 25 {b}^{4}$

We can factor out a $5$ from both terms. Here we are essentially dividing, and we get

$5 \left(7 {x}^{3} - 5 {b}^{4}\right)$

as our final answer

Hope this helps!
