A company rents cars. The company charges a fee of $15 per day plus $0.20 per mile. The company also charges $10 per day for insurance. Jerry rented a car for x days. Jerry drove the car 644 miles. Write an equation that could be used to determine the total charge, y, for Jerry to rent the car.

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
