Best ResponseYou've already chosen the best response.0Assuming p is a real number, p^2 = a, 2p = b and c = 1, because they are all constants.

Best ResponseYou've already chosen the best response.0x is the x in the quadratic equation. It will become:\[x = (2p \pm \sqrt{(2p)^{2}  4p^{2}})/(2p^{2})\]

Best ResponseYou've already chosen the best response.2Actually, it's just (px)^2 + 2px + 1 = 0. We can just easily factor this especially since C here only has (1)(1) as its factors. (px + 1)(px + 1). :)

Best ResponseYou've already chosen the best response.0a quadratic equation can be written in the form:\[ax^2 + bx + c = 0\]then we get\[a = p^2\]\[b = 2p\]\[c = 1\]after that you just need to plug them to the quadratic formula\[x = \frac{b \pm \sqrt{b^2  4ac}}{2a}\]
