Question

Find all values for x that must be excluded from the domain of the expression:
2x(x + 1)/3x2 + 5x + 2

Answer 1

Oops, wrote it wrong.

Answer 2

Did you mean?
\[\huge \frac{\frac{2x}{x + 1}}{3x^2} + 5x + 2\]

The obvious part here is that no denominator must = 0, but first I would simplify.

Answer 3

You will have to exclude anything that causes a "divide by zero" error when you have this in simplified form. :-)

Right now those two things are

x+1=0
x=-1

and

3x^2 = 0
x^2=0
x=0

Answer 4

Thanks!
