Using the quadratic formula to solve 7 x squared minus x is equal to 7 , what are the values of x ?

Write the equation in standard form: 7x² − x − 7 = 0, so a = 7, b = −1, and c = −7. The quadratic formula gives x = (1 ± √[(-1)² − 4(7)(−7)]) / 14 = (1 ± √197) / 14. Therefore, the solutions are the fraction with numerator 1 plus or minus √197 and denominator 14.
