Question

The equation 2x^2x-1-2x+73+4-6xx-1+1=0 can be transformed by eliminating fractions to the equation x^2-5x+4=0. The roots of the latter equation are 4 and 1. Then the roots of the first equation are:

Accepted Answer

We plug x=4, x=1 into the original equation x=48-3+153+-20-315+20-84+1=0 x=120-93+-20+1=0, which is undefined because k0 is undefined. Thus the only solution to the equation is x=4, only 4
