Best Answer

x2 + 3px + p = 0

x2 + p(3x + 1) = 0

p(3x+1) = -x2

p = -x2/(3x+1)

So p can have any value at all. In fact, around x = -1/3, p goes asymptotically to + and - infinity.

Q: X2 plus 3px plus p equals 0 what is p?

x2 + 7x = 2x2 + 6 x2 - 2x2 + 7x = 6 -x2 +7x - 6 = 0 or alternatively x2 - 7x + 6 = 0

x2 + 49 = 0 ∴ x2 = -49 ∴ x = 7i

x2 + 10x = 0 x2 + 10x + 25 = 25 (x + 5)2 = 25 x + 5 = +-5 x1 = 0 x2 =10

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)
