I suggest you use the quadratic formula. In this case, a = 1, b = 5, c = 3.
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.
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
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
7
If you mean: 3x+2y+6 = 0 then it is y = -1.5x-3 as a straight line equation
2z+6z+24=0 8z+24=0 8z= -24 z= - 3
correct anser is C ; y=-45
(4 ± i2) where i2 = -1
if it is =0, you can divide the whole equation by 5 to leave 2y+3=0
3x2 + 17x + c = 0, rearranging gives c = -3x2 - 17x
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.
6x + 5 = 0 (I'm assuming) 6x = -5x = -5/6
If you mean: x squared+9x+14 = 0 then by using the quadratic equation formula x = -2 or x = -7
