a) 0.92%
b) 0.38%
c) 3.85%
d) 0.15%

step-by-step :

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

my guess would be b and d, but i didn’t actually get out the pen and paper. lol
