    Expand the right hand side out, and compare coefficients of the terms.

    Well, on both sides of the equations you have terms involving x^2, x and just constants. For the two equations to be equal, these coefficients must be the same. Let me give a simple example. Say you have the following:

    5x^2 + 7x + 11 = ax^2 + bx + c

    For this to be true, we must have that a=5, b=7 and c=11. You can apply the same logic to your equation. If you need any more guidance/help, let me know!

    Take out the 3 and the complete the square or expand the equation on the right hand side and compare coefficients

    If I do complete the square then p won't = 3 will it?
