Amaya enters a competition to guess how many candies are in a jar. Amaya’s guess is 115 candies. The actual number of candies is 125. What is the percent error of Amaya’s guess?

it's both, now can you answer my most recent question?

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

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
