I suggest you use the quadratic formula. In this case, a = 1, b = 5, c = 3.
Let y=ce^(rx). R^2+r+1=0. Quadratic equation to find R.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
A quadratic equation. If you wish to solve for x, you can do so as follows: -x2 + 6x + 7 = 0 x2 - 6x - 7 = 0 (x - 7)(x + 1) = 0 x ∈ {-1, 7}
X2+11x+11 = 7x+9 X2+11x-7x+11-9 = 0 x2+4x+2 = 0 Solve as a quadratic equation by using the quadratic equation formula or by completing the square: x = -2 + or - the square root of 2
