4x^211x+3=5x+4 How do I solve this?

4 x^2  16 x  1 = 0
x = [ 16 +/ sqrt (256 + 16) ] / 8
x = [ 16 +/  sqrt (16*17) ] / 8
x = 2 +/  .5 sqrt 17
by the way by inspection you can see that it is going to be very close to
4 x^2  16 x = 0
x(x4) = 0
x = 4 or 0

Okay Ms. Sue. I am in 8th grade but I am taking Algebra with 9th graders. I am very confused with my previous problem. I have asked my Dad but we are both getting confused. Now I have come up with 22. Is this my correct answer?
