ottcomn · Accepted Answer

The restriction on the variable for rational expression 6c7a3b2 are a ≠ 0 and b ≠ 0.  Given Information:   The provided rational expression is 6c7a3b2.  Formula used:  The standard form of rational expression is p(x)q(x).  Where, p (x) and q(x) are polynomial and q(x) ≠ 0.  Calculation:  Consider the rational expression, 6c7a3b2.  For the expression 6c7a3b2, if a=0 were substituted for a, the denominator would be zero.  If b=0 were substituted for b, the denominator would be zero.  Hence, for this expression 6c7a3b2, a ≠ 0 and b ≠ 0   If, either a or b were zero. Then the product would be zero.  Therefore, the restriction on the variable for rational expression 6c7a3b2, are a ≠ 0 and b ≠ 0.
