x2+2x-4 = 0
x = (-2 plus/minus sqrt (4-(4x1x-4)) / 2
x = (-2 plus/minus sqrt 20)/2
x = (-2 - sqrt 20)/2 or (-2 + sqrt 20)/2
x = -3.236 or 1.236

How do you solve x2 81 equals 0?
x: x2 - 81 = 0
Solve for x - x2-9x plus 14 equals 0?
x - x2 - 9x + 14 = 0 ; whence, x2 + 8x = 14 , x2 + 8x + 16 = 30 , and x + 4 = ±√30 . Therefore, x = ±√30 - 4 .

How do you answer the problem x2 plus 10x plus equals 0?
x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10
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)
