Simplify the expression completely if possible.

(6x^2 + 54x)/3x^2

To simplify the expression (6x^2 + 54x)/3x^2 completely, we can simplify both the numerator and denominator separately.

For the numerator, we can factor out 6x:
6x^2 + 54x = 6x(x + 9)

For the denominator, we can factor out 3x^2:
3x^2 = 3x * x

Now, we can cancel out the common factor of 3x:
(6x^2 + 54x)/3x^2 = (6x(x + 9))/(3x * x) = (2(x + 9))/(x)

So, the completely simplified expression is 2(x + 9)/x.
