Week 10- discriminant

The discrimination is the formula b^2-4(a)(c) and this formula helps us determie the nature of the roots of a quadratic formula. After completing the equation if the awnser is positive than there are 2 different real roots, if the anwser ends up to be zero then that means there are 2 equal real roots and finally if the anwser is negative there are no real roots because you can not evaluate square roots of a negative number.

Ex: 5x-7x+10

(7)^2-4(5)(10)

49-250

-201

since it’s negative there are no real roots.
