It's a second degree equation in 'x' that has no real solution.
No real number in the place of 'x' can make that equation a true statement.
There are only two "imaginary" numbers that 'x' can be:
+ 4i sqrt(5)
- 4i sqrt(5)
It is: 3x2+6x-11 = 0
63828
It is a quadratic equation.
4
It is a quadratic equation in the variable x.
It is: 3x2+6x-11 = 0
Solve this problem -x squared -40x- 80 =0
63828
It is a quadratic equation.
True. Both equations can be factored to x(x+4)=0 and 3x(x+4)=0, respectively. Therefore, the solutions for both equations are x=0 and x=-4. So, yes, the solutions are identical because math doesn't play favorites.
x = -½
4
It is a quadratic equation in the variable x.
1
If you mean: x2+9x+20 then it is (x+4)(x+5) = 0 when factored
4, -5
3x(2x + 1)
