I have a test, it is 8 questions, but the total points are 15. I got 9.38/15, how many wrong?

I believe three.

Step-by-step explanation:

15 / 8 = 1.875

9.38 / 1.875 = 5.002

Brainliest would be appreciated!

2 x^2 -3x+p

sum of roots = 3/2

let other root be x

3+ x = 3/2

x= 3/2 - 3 = -3/2

product of roots = p/2

3× -3/2 = p/2

-9 = p

⭐⭐
