Question

Simplify. Identify any x value for which the expression is undefined x^2+3x/x^3

Answer 1

x = 0

Explanation:

I think you mean

`(x^2 + 3x)/(x^3)`

The only undefined values of x come from the denominator, x^3.

A denominator cannot equal zero since division by zero is undefined.

Therefore if x^3 equals zero, you get an un defined expression.

We let x^3 = 0 and solve for x to find the values of x that would cause an undefined expression.

x^3 = 0

Solve for x by taking the cubic root of both sides.

x = 0

Answer: x = 0
