Step-by-step explanation:
The quadratic can be solved in a straightforward way:
![x^2+4=0\\\\x^2=-4\qquad\text{subtract 4}\\\\x=\pm\sqrt{-4}\qquad\text{take the square root}\\\\x=\pm2i\qquad\text{simplify}](https://tex.z-dn.net/?f=x%5E2%2B4%3D0%5C%5C%5C%5Cx%5E2%3D-4%5Cqquad%5Ctext%7Bsubtract%204%7D%5C%5C%5C%5Cx%3D%5Cpm%5Csqrt%7B-4%7D%5Cqquad%5Ctext%7Btake%20the%20square%20root%7D%5C%5C%5C%5Cx%3D%5Cpm2i%5Cqquad%5Ctext%7Bsimplify%7D)
This tells you that the solutions are ...
2i or -2i
__
For each root of "a", (x -a) is a factor. Thus the factors of the equation are ...
(x +2i)(x -2i)

Answer:
y = ½x + 6.
Step-by-step explanation:
You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6.
