What operations of rational expressions require a common denominator?
addition and subtraction, you dummy
in order to subtract two rational expressions by simply subtracting the numerator you must make sure what is equal?
To subtract two rational expressions by simply subtracting the numerators, the denominators of the expressions must be equal. This ensures that the fractions are equivalent in terms of their base values, allowing for direct subtraction. If the denominators are not the same, you would need to find a common denominator before performing the subtraction.
If the equation of a function is a rational expressions the function is rational?
