for the quadratic in standard form f(x) = ax^2 + bx + c
---
one real solution, or two real solutions, or two complex solutions (depending on the values of a, b, and c), can be found by using the quadratic formula.
---
a fast way to quadratic equations is by using this solver:
---
for example:
2x^2 - 8x - 120 = 0
---
the above quadratic equation is in standard form, with a=2, b=-8, and c=-120
---
to solve the quadratic equation, by using the quadratic formula, copy and paste this:
2 -8 -120
into this solver: https://sooeet.com/math/quadratic-equation-solver.php
---
the two real roots (i.e. the two x-intercepts), of the quadratic are:
x = 10
x = -6
