Answer
The simplified form is \( \frac{x+12}{x^{2}+2x} \).
Solution
Calculate or simplify the expression \( \frac{6}{x}-\frac{5}{x+2} \).
Simplify the expression by following steps:
- step0: Solution:
\(\frac{6}{x}-\frac{5}{x+2}\)
- step1: Reduce fractions to a common denominator:
\(\frac{6\left(x+2\right)}{x\left(x+2\right)}-\frac{5x}{\left(x+2\right)x}\)
- step2: Rewrite the expression:
\(\frac{6\left(x+2\right)}{x\left(x+2\right)}-\frac{5x}{x\left(x+2\right)}\)
- step3: Transform the expression:
\(\frac{6\left(x+2\right)-5x}{x\left(x+2\right)}\)
- step4: Multiply the terms:
\(\frac{6x+12-5x}{x\left(x+2\right)}\)
- step5: Subtract the terms:
\(\frac{x+12}{x\left(x+2\right)}\)
- step6: Multiply the terms:
\(\frac{x+12}{x^{2}+2x}\)
The simplified form of the expression \(\frac{6}{x}-\frac{5}{x+2}\) is \(\frac{x+12}{x^{2}+2x}\).

To subtract the fractions \(\frac{6}{x}\) and \(\frac{5}{x+2}\), we need a common denominator, which is \(x(x+2)\). Rewriting the fractions: \[ \frac{6}{x} = \frac{6(x+2)}{x(x+2)} = \frac{6x + 12}{x(x+2)} \] \[ \frac{5}{x+2} = \frac{5x}{x(x+2)} \] Now, we can perform the subtraction: \[ \frac{6x + 12}{x(x+2)} - \frac{5x}{x(x+2)} = \frac{(6x + 12 - 5x)}{x(x+2)} = \frac{x + 12}{x(x+2)} \] Thus, the simplified answer is: \[ \frac{x + 12}{x(x + 2)} \]
