Can someone please help me with this problem?

The solutions of x(2x-7)=3 may be expressed in the form m+sqrt{n}/p and m-sqrt{n}/p, where m, n, and p are relatively prime numbers. Find m+n+p.

Start with:  x(2x - 7)  =  3

Solve:          2x2 -7x  =  3

              2x2 - 7x - 3  =  0   

Use the quadratic formula with a = 2, b = -7, and c = -3:

      x  =  [7 +/- sqrt(73) ] / 4

 

From this answer, pick out m, n, and p and use these values to get the answer.
