Caleb wants to buy a package of Skittles. Which is the better value? A. 8 oz. for $1.60

B. 10 oz. for $1.80

C. 12 oz. for $2.04

D. 15 oz. for $3.50

I think 8 oz. of skittles is better cause it's the same as 10 oz but 8 oz is cheaper

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
