The number of solutions of a quadratic equation
ax^2+bx+c=0
Depends on its discriminant
/Delta=b^2-4ac
If /Delta>0 there are two distinct solutions
If /Delta=0 there are two coincident solutions
If /Delta<0 there are no solutions.
We know that there are two real solutions (I assume you mean distinct solutions), so we know that the discriminant is positive:

Answer: 72
Step-by-step explanation:
(8-(2-2))×9
First do (2-2=0)
(8-0=8)
8×9=72
Hope this helps
It is 24+6b im writing more because it says to put more cause my answer is to "short"
