If you mean: 3x+2y+6 = 0 then it is y = -1.5x-3 as a straight line equation
correct anser is C ; y=-45
(4 ± i2) where i2 = -1
2z+6z+24=0 8z+24=0 8z= -24 z= - 3
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
You would set the equation equal to 0 and then solve for x. You may get one or several answers for x, x being the number(s) that make the equation equal 0.
1 + 19 + 0 + 1 = 21
By using the quadratic equation formula: x = -5 and x = 3
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
s^2 +4x -21 = 0 is a quadratic equation and by using the quadratic equation formula its solutions are s = 3 or s = -7
Solve f(x) =0 or y = 0 (depending on how the equation is given).
I suggest you use the quadratic formula. In this case, a = 1, b = 5, c = 3.
It cannot be solved because the discriminant of the quadratic equation is less than zero
x2-8x+12 = 0 (x-2)(x-6) = 0 x = -2 or x = -6
That is not a correct equation. The numbers on the left equal -16, not 0. This is an equation with no solution.
x2+x-15 = 0 Using the quadratic equation formula: x = 3.405124838 or x = -4.405124838
