1. The equation x^2 +6px+p =0, where p is a non zero constant, has equal roots. Find the value of p.
2. If a quadratic equation has:
real roots then b^2 - 4ac > 0
equal roots then b^2 - 4ac = 0
no roots then b^2 - 2ac < 0

You need to know these 3 basic expressions called discriminants for quadratic equations.

Back to your question, if it has equal roots then which of the 3 equations above would you use? Substitute it in and you'll get your value of p!
