Simplify. x/7x+x^2
A. 1/7+x; Where x does not equal -7
B. 1/7x; Where x does not equal 0
C. 1/7+x; Where x does not equal 0,-7
D. 1/7
I get C

To simplify the given expression x/7x + x^2, we first need to factor out the greatest common factor (GCF) from the numerator.
The GCF of x and x^2 is x, so we can rewrite the expression as:
x(x + 1)/(7x + x^2)
Now, let's look at the denominator. We can factor out x from the terms 7x and x^2:
x(x + 1)/(x(7 + x))
Next, we can cancel out the x terms in the numerator and denominator:
(x + 1)/(7 + x)
Now, we can rearrange the terms in the numerator and denominator to simplify further:
(1 + x)/(7 + x)
This simplified expression matches option C: 1/7 + x where x does not equal 0 or -7.
