To simplify the expression √x - 2/x + 3, we need to find a common denominator for the fraction part of the expression.

The common denominator for x and 3 is x.

So, we can rewrite the expression as (√x - 2x)/x + 3.

Now, we can combine the terms in the numerator by finding a common denominator for √x and 2x.

The common denominator for √x and 2x is 2x.

So, we can rewrite the numerator as (√x * 2x - 2x)/x + 3.

Simplifying the numerator, we get (2√x * x - 2x)/x + 3.

Further simplifying, we have (2x√x - 2x)/x + 3.

Now, we can divide each term in the numerator by x to simplify further.

The simplified expression is 2√x - 2.
