---
x^2 - 5x - 1 = 0
---
the above quadratic equation is in standard form, with a=1, b=-5, and c=-1
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
1 -5 -1
into this solver: https://sooeet.com/math/quadratic-equation-solver.php
---
the quadratic has two real roots at:
---
discriminant = 29
---
root 1:
x = ( 5 + sqrt( 29 ) ) / 2
x = 5.19
---
root 2:
x = ( 5 - sqrt( 29 ) ) / 2
x = -0.19
