You can work this out by using what we call "imaginary" numbers. By definition, imaginary numbers are numbers that when squared, will produce a negative value. Usually these are represented by multiplying real numbers by a constant called "i", which is defined as the square root of negative one.
In this case the answer will be:
x2 + 144 = 0
∴ x2 = -144
∴ x = -1441/2
∴ x = 1441/2 * -11/2
∴ x = 12i
144 + 0
It is: 3x2+6x-11 = 0
63828
It is a quadratic equation.
True because in both equations x = 0 or x = -4
144 + 0
144
It is: 3x2+6x-11 = 0
63828
It is a quadratic equation.
True because in both equations x = 0 or x = -4
x = -½

x2 - 4x - 96 = 0 (x - 12)(x + 8) = 0 x = 12, -8 Check it. 144 - 48 - 96 = 0 64 + 32 - 96 = 0 It checks.
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
