You can put this solution on YOUR website!
12x^2 + 3x -58.5 = 540
12x%5E2+%2B+3x+-58.5+=+540


Try whatever simplification, and maybe use general quadratic formula solution.


or, this ...
12x%5E2%2B3x=540%2B58.5
12x%5E2%2B3x=598.5
4x%5E2%2Bx=199.5
.
4x%5E2%2Bx-199.5=0
discrim, 1%2B4%2A4%2A199.5=3193

x=%28-1%2B-+sqrt%283193%29%29%2F16
