To find the discriminant we have to use $b^2 -4(a)(c)$

we plug in the numbers and when we find the answer that is our discriminant.

The discriminant tells us how many roots our equation has…

so if x>0 we have two roots

if x=0 we have one root

if x<0 we have no roots

so in this equation above, we have two roots
