the value of dependent variable is always said to be dependent on the independent variable of math equation. For example, the equation y=3x+4, the value of variable 'y' changes according to the changes in the value of 'x'. Therefore, the variable 'y' is the dependent variable.
Let x = your number.
6x = x^2 - 27. Subtract 6x from each side.
0 = x^2 - 6x - 27. Factor
0 = (x-9) (x+3). Set each term equal to zero
(x+3) = 0. Subtract 3 from each side.
x = -3. This is the negative solution.
(x-9) = 0. Add 9 to each side.
x = 9. This is the positive solution.
