Q. Simplify. Express your answer as a single fraction in simplest form. qr−q4
Identify common denominator: Identify the common denominator for the fractionsr/q and 4/q. Since both fractions already have the same denominator q, the common denominator is q.
Combine numerators: Combine the numerators of the fractions while keeping the common denominator. This gives us (r−4)/q.
Check for further simplification: Check if the numerator can be simplified further. Since r is a variable and 4 is a constant, they cannot be combined any further. Therefore, the expression is already in its simplest form.
