To find the discriminant in a quadratic equation ax^2 + bx + c = 0, just use the formula b^2 - 4ac. Easy peasy!
b^2 - 4ac. That's it. You're welcome!
As a math tutor, I always tell my students: Just remember b squared minus 4ac, and you'll find the discriminant in no time!
Plug in the coefficients into b^2 - 4ac. For example, if your equation is 2x^2 + 3x - 5 = 0, you'd do (3)^2 - 4(2)(-5).
