Ah, just crack my minds...weird, finding quadratic equations

Hai, everyone..nice to meet u all and thanks 4 all those had put efforts to answer my question...okay, this one I find it accidentally and I'm quite curious about it, do anyone(s) can help me out?? Thanks...(Hi)

1) Form a quadratic equation with roots which exceed by 2 the roots of the quadratic equation 3x^2 - (p - 4)x - (2p + 1) = 0.

Find the values of p for which the given equation has equal roots.

I'm just manage to find until half of the solutions and don't know how to find p??..Could someone help me...(Wondering)
