Step 1:I'll solve this step by step, carefully following the LaTeX formatting guidelines:
Step 2:: Identify the Problem
We need to subtract two fractions with different denominators: $$\frac{2}{x+10} - \frac{3}{x+4}
Step 3:: Find the Least Common Denominator (LCD)
The LCD will be the product of the denominators: $$(x+10)(x+4)
Step 4:: Rewrite Each Fraction with the LCD
\frac{2}{x+10} = \frac{2(x+4)}{(x+10)(x+4)}
\frac{3}{x+ 4} = \frac{3(x+ 10)}{(x+ 10)(x+ 4)}
Step 5:: Subtract the Fractions
\frac{2(x+4) - 3(x+10)}{(x+10)(x+4)}
Step 6:: Simplify the Numerator
\frac{2x + 8 - 3x - 30}{(x+10)(x+4)}
\frac{-x - 22}{(x+ 10)(x+ 4)}
Final Answer
Note: The domain of this expression excludes x = - 10 and x = - 4 to avoid division by zero.
