solve 1-(2/x)=2/(x+2) Express your answer in simplest radical form. What is radical form ne how? 1-(2/x)=2/(x+2) Multiply both sides by x(x+2): x(x+2) - 2(x+2) = 2x Note that we cannot allow x to be 0 or minus two because for these values the original equ...

find the x-intercepts of y=3x^2-6x by factoring y = 3x^2 - 6x Factor out 3x: y = 3x(x - 2) Set each factor equal to 0: 3x = 0; x = 0 x - 2 = 0; x = 2 Those are your x-intercepts. I hope this will help.
