Answer:
= 6x(x² +x +1)
Explanation:
This is asking for an equivalent expression. One way to make an equivalent expression is to factor the one that is given. When you examine the terms of this expression, you see that every term has a coefficient of 6. Thus 6 is a factor of the whole expression, and we can rewrite it as ...
= 6(x³ +x² +x)
At this point, you can see that x is also a factor of every term. This lets us rewrite the expression as ...
= 6x(x² +x +1)
There are no more common factors of all the terms.
