Best Answer

x2 + 20x + 4 = 0

x2 + 20x + 100 = 96

(x + 10)2 = 96

x + 10 = ±961/2

x = -10 ±961/2

x = -10 ±4√6

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)


What number must you add to complete the square of x2 plus 20x equals 39?

x2 + 20x - 39 = 0: Add 61 giving: x2 + 20x + 100 = (x + 10)2


X2 plus 36 equals 20x?

x2 + 36 = 20x so x2 - 20x + 36 = 0 so x2 - 2x - 18x + 36 = 0 or x(x - 2) - 18(x - 2) = 0 that is (x - 2)(x - 18) = 0 so x - 2 = 0 or x - 18 = 0 ie x = 2 or x = 18
