Solve with quadratic formula 8x^2-9x-5=0

Answers

8x^(2) - 9x - 5 = 0

x = \frac{-(-9) +/- \sqrt{(-9)^(2) - 4(8)(-5)}}{2(8)}

x = (9 +/- √(81 + 160))/(16)

x = (9 +/- √(241))/(16)

x = (9 +/- 15.524)/(16)

x = 0.5625 +/- 0.97025
x = 0.5625 + 0.97025                                   x = 0.5625 - 0.97025
x = 1.53275                                                  x = -0.40775
