3 minutes - 2 minutes = 1 minute

30 gallons - 12 gallons = 18 gallons

 it is draining at 18 gallons per minute

equation would be: y = -18x

The difference between roots of the quadratic equation x^2+x+c=0 is 6. find c.
DiKsa [7]

Answer:

\displaystyle c = -\frac{35}{4} = -8.75.

Step-by-step explanation:

Let the smaller root to this equation be m. The larger one will equal m + 6.

By the factor theorem, this equation is equivalent to

a(x - m)(x - (m+6))= 0, where a \ne 0.

Expand this expression:

a\cdot x^{2} - a(2m + 6)\cdot x + a(m^{2} + 6m) =0.

This equation and the one in the question shall differ only by the multiple of a non-zero constant. It will be helpful if that constant is equal to 1. That way, all constants in the two equations will be equal; (m^{2} + 6m) will  be equal to c.

Compare this equation and the one in the question:

The coefficient of x^{2} in the question is 1 (which is omitted.) The coefficient of x^{2} in this equation is a. If all corresponding coefficients in the two equations are equal to each other, these two coefficients shall also be equal to each other. Therefore a = 1.

This equation will become:

x^{2} - (2m + 6)\cdot x + (m^{2} + 6m) =0.

Similarly, for the coefficient of x,

\displaystyle -(2m +6) = 1.

\displaystyle m = -\frac{7}{2}.

This equation will become:

x^{2} + x + \underbrace{\left(-\frac{35}{4}\right)}_{c} =0.

c is the value of the constant term of this quadratic equation.
