X squared + 4 = 0 , to solve this, you would need to carry the 4 over, so X squared = -4, then move the square over so x = +4i,-4i , because when you divide the negative, it creates a imaginary -1

What is the point of intersection of the parabolas y equals x2 plus 20x plus 100 and y equals x2 -20x plus 100 showing work?
If: y = x2+20x+100 and x2-20x+100 Then: x2+20x+100 = x2-20x+100 So: 40x = 0 => x = 0 When x = 0 then y = 100 Therefore point of intersection: (0, 100)
