Trying to prepare a budget. Chester has done research and found that he spends an average of $120 on his phone/internet/cable service, $277 on his electric bill, and
$299 on his health insurance premium. If he earns $2800 per month, estimate the amount of money he will have after paying these bills each month.

step-by-step explanation:

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
