Andrew was working on a project for Science class. He began working on the project at 10:32 a. m. When he finally finished, the clock read 2:15 p. m. How long did it take Andrew to complete the project?

3 hours 43 minutes

3 hours and 43 minutes = 223 minutes

Step-by-step explanation:

is there more to this 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
