Question

Simplify each expression. State any excluded values.
x^2 + 6x + 9 / 5x + 15

I have trouble simplifying expressions. I don't know where to start. Help!

Answer 1

well look at factoring the numerator and denominator

\[\frac{(x + 3)^2}{5(x + 3)}\]

so you need to look at the value you can exclude in the denominator

its found by solving

x + 3 = 0

Answer 2

The top part would be
\[{ x + 9 }\]
right? So, what's the other?

Answer 3

x+9?

Answer 4

Are you questioning my answer or..?
I really don't understand.

Answer 5

what is the x+9 for?

Answer 6

Well, 3^2 is 9 right?
