Answer a^3-3a
a^2 times a = a^3 you add exponents
The correct answer is x=3. Hope this helps!!
we know that
<u>The Division Property of Equality</u> states that if you divide both sides of an equation by the same number, both sides of the equation will remain equal
so
in this problem we have

Solve for x
Using the Division Property of Equality, Divide by
both sides


therefore
<u>the answer is the option</u>
