Evaluate the expression if a = 4 , b = 9. and c = 1. a. –27 b. –9 c. 9 d. 27
( : )

I don't know if you want to find this answer using the quadratic formula or not, the question is no the greatest but i will solve it the best that i can. Or

Step-by-step explanation:

I used the discriminant which is √-4ac

Then I filled the numbers in, and found that 9 gets plug in for b and this becomes 9 squared, and that becomes 81. 4 is multiplied to 4 and 1 and becomes 16. Then 81 and 16 are subtracted and we get 65. We then find the square root, and will find that the answer is C.

Hoped this helped thanks, if you need more help let me know.

a=r

d=q

c=p

b=s

hope this !
