Answer:

  • 3x² is a term in the numerator
  • x + 1 is a common factor
  • The denominator has 3 terms

Explanation:

You can identify terms and count them before you start factoring. Doing so will identify 3x² as a term in the numerator, and will show you there are 3 terms in the denominator.

When you factor the expression, you get ...


(3x^2-3)/(3x^2+2x-1)=(3(x^2-1))/((3x-1)(x+1))=(3(x-1)(x+1))/((3x-1)(x+1))

This reveals a common factor of x+1.

So, the above three observations are true of this rational expression.
