Solution steps

One step at a time

6x−1 −3x+1

Least Common Multiplier of x−1, x+1: (x−1)(x+1)

Adjust Fractions based on the LCM

=6(x+1)(x−1)(x+1) −3(x−1)(x−1)(x+1)

Apply the fraction rule: ac −bc =a−bc

=6(x+1)−3(x−1)(x−1)(x+1)

Simplify 6(x+1)−3(x−1): 3x+9

=3x+9(x−1)(x+1)

Solve instead

f(x)=6x−1 −3x+1
