Use quadratic formula to solve
8x²-2x=7

8x^2 - 2x -7

2(+/-) the square root of (4-224), all divided by 16

- simplified form is 1 (+/-) 2i times the square root of 55, all divided by 8

8x^2 - 2x -7 = 0                Subtract 7 on both sides in order to get 0

Quadratic Formula:    -b +/- radical(b^2 - 4ac)
                                 
                                               2a

So, inputting the numbers from the equation, you would get: 
1.
2 +/- radical(-2^2 - 4(8)(-7))

                 2(8)

2.  
2 +/- radical(4 +224)

              16

3. 
2 +/- radical(228)

          16

4.
2 + radical(228)                1      radical(228)
   =>     ---  +          
           16                       8            16

2 - radical(228)                1      radical(228)
   =>      ---  -  
       16                           8          16

If you chose to, you could simplify radical(228)
