Answer:

False

Explanation:

Given expression: x/(x - 3) + (x - 3)/x

First, we need to find a common denominator to combine the two fractions. The common denominator is x(x - 3):

x/(x - 3) = (x * x)/[x * (x - 3)] = x^2 / (x^2 - 3x)

(x - 3)/x = (x - 3) * (x - 3)/[x * (x - 3)] = (x^2 - 6x + 9) / (x^2 - 3x)

Now, the expression becomes:

x^2 / (x^2 - 3x) + (x^2 - 6x + 9) / (x^2 - 3x)

Combine the fractions with the common denominator:

(x^2 + x^2 - 6x + 9) / (x^2 - 3x)

Simplify the numerator:

(2x^2 - 6x + 9) / (x^2 - 3x)

Now we are given that this expression is equal to 5/2:

(2x^2 - 6x + 9) / (x^2 - 3x) = 5/2

Cross-multiply:

2 * (2x^2 - 6x + 9) = 5 * (x^2 - 3x)

Simplify both sides:

4x^2 - 12x + 18 = 5x^2 - 15x

Subtract 4x^2 and add 15x to both sides:

18 = x^2

Take the square root of both sides:

x = ±√18

Simplify the square root:

x = ±3√2

So, the solutions for x are x = 3√2 and x = -3√2.

However, when you plug these solutions back into the original expression, you'll find that they do not satisfy the equation x/(x - 3) + (x - 3)/x = 5/2. Therefore, there seems to be an error or misunderstanding in the equation provided. The equation does not hold true for the given expression.
