Question
Solve the inequality
Solve the inequality by testing the values in the interval
Solve the inequality by separating into cases
−32<x<21
Alternative Form
x∈(−32,21)
Evaluate
2x−1x−4>2
Find the domain
More Steps

Evaluate
2x−1=0
Move the constant to the right side
2x=0+1
Removing 0 doesn't change the value,so remove it from the expression
2x=1
Divide both sides
22x=21
Divide the numbers
x=21
2x−1x−4>2,x=21

−2x−13x+2
−2x−13x+2>0
Change the signs on both sides of the inequality and flip the inequality sign
2x−13x+2<0
Set the numerator and denominator of 2x−13x+2 equal to 0 to find the values of x where sign changes may occur
