I suggest you use the quadratic formula. In this case, a = 1, b = 5, c = 3.

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}

Let y=ce^(rx). R^2+r+1=0. Quadratic equation to find R.

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

There is no equation (nor inequality) in the question. There is also no unknown variable. So there is nothing to solve.

Using the quadratic equation formula:- x = 3.795831523 or x = -5.795831523

The equation has no solution. Since if you combine like terms, you get 0=-10 which isn't true, there are no solutions to the equation.
