Question 384935: Solve: 8/(x+2)+8/(x-2)=3 ok I have been working and working on this and it comes up (8x+16)+ (8x--16)=3 then iwent 24+-8 = 3 but something is wrong we are working on quadratic and rooting. Please help!!
Here's another one I'm stuck with,Solve by factoring and using the principle of zero products:
2x^2-11x+15=0
So I did this 2(x-2)(x+2)-11+15 then add 11 on both sides which would be 2x2=4 and 15+11 =4 -11+11=0 But does not make any since.
