Identify Factors: Identify common factors in the numerator and the denominator.Numerator: 4x2+1Denominator: x3−4x=x(x2−4)=x(x−2)(x+2)No common factors between numerator and denominator.
Simplify Expression: Simplify the expression by canceling out common factors, if any.Since there are no common factors, the expression remains as (4x2+1)/(x(x−2)(x+2)).
Check Restrictions: Check for any restrictions in the values of x.x cannot be 0, 2, or −2 because these values would make the denominator zero, which is undefined.
