If the same person replaces the shower head with a low-flow shower head that has a flow rate of 1.5 gallons per minute, how much water will be saved in a year? Assume the length and frequency of showers does not change.

the square root of what number? if you add that, then someone will probably answer the 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
