## 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.
