Q. Perform the operation and express your answer as a single fraction in simplest form.21−x1Answer:
Identify Common Denominator: Identify the common denominator for the fractions.Since we have the fractions 21 and x1, the common denominator will be 2x.
Rewrite with Common Denominator: Rewrite each fraction with the common denominator. (21) becomes (2xx) and (x1) becomes (2x2).
Perform Subtraction: Perform the subtraction using the common denominator. (2xx)−(2x2)=2xx−2
Check for Simplification: Check if the resulting fraction can be simplified further. The numerator (x−2) and the denominator (2x) do not have any common factors other than 1, so the fraction is already in simplest form.
