The equation is -x2 - 4 = 14 or -x2 = 18 which is the same as x2 = -18. That is the quadratic equation.
You don't have an equation there.

5. A circle with centre (0,0) has equation: x2 + y2 = radius2 With: x2 + y2 = 25 = 52 The radius is 5.
x2 = 657.4096
y2=-x2-8x+6
(x-2)^2+y^2=64
The equation is -x2 - 4 = 14 or -x2 = 18 which is the same as x2 = -18. That is the quadratic equation.
The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.The equation of a circle centered at the origin is x2 + y2 = r2; in this case, x2 + y2 = 64.
it is not an equation (there no equality in it!)
what number do you add in the equation x2-16x=23
The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
Without an equality sign the expression given can't be considered to be an equation.
