60 gallons of the whole thing, chlorine and water mixed.
one may note that 30 is half of 60, namely 50% of 60.
if there are 30 gallons of chlorine, 60 - 30, the leftover is 30 gallons, and that must be water.
so 50% is chlorine, and the other 50% is water.

Answer:
X² - 14x + 48= 0
Step-by-step explanation:
To find the quadratic equation well have to look for the root of the equation.
So the roots are at x= 6 and x= 8
The quadratic curve didn't pass the origin .
It intercepted the x axis at 6 and 8 and that's the roots.
So our equation is
(X-6)(x-8)= x²-8x -6x +48
X² - 14x + 48= 0
