Determine the polynomial equivalent to this expression.
gregori [183]

Answer:

\dfrac{x^2-9}{x-3}= \Large \boxed{x+3}

Step-by-step explanation:

Hello,

We need to work a little bit of the expression to see if we can simplify.

Do you remember this formula?

   for any a and b reals, we can write

   a^2-b^2=(a-b)(a+b)

We will apply it.

For any x real number different from 3 (as dividing by 0 is not allowed)

\dfrac{x^2-9}{x-3}=\dfrac{x^2-3^2}{x-3}=\dfrac{(x-3)(x+3)}{x-3}=x+3

So the winner is C !!

Hope this helps.

Do not hesitate if you need further explanation.

Thank you
