Adding and Subtracting
Simplify the expression . First, factor the quadratic denominator to find the Least Common Denominator (LCD). It factors as , making this the LCD. Rewrite each expression using the common denominator: multiply the numerator and denominator of the first term by to get and multiply the second term by to get . The third term already has the LCD. Combine the expressions into a single fraction: . Distribute across the numerators to get . Combine like terms to simplify the numerator to . Factor out the greatest common factor, , to yield . The fraction is now . Divide out the common factor of , resulting in the final simplified expression .
