ax2+bx+c = 0 is the general form of a quadratic equation which normally has two solutions
It is: 3x2+6x-11 = 0
63828
It is a quadratic equation.
True because in both equations x = 0 or x = -4
4
It is: 3x2+6x-11 = 0
63828
It is a quadratic equation.
True because in both equations x = 0 or x = -4
x = -½
4
It is a quadratic equation in the variable x.
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
4, -5
3x(2x + 1)
(x + 3)(x + 2)
(2x-4)(x-1) = 0
