Given that for all values of x:

3x^2 + 12x + 5 = p(x +q)^2 + r

a) find the values of p, q and r

b) solve the equation 3x^2 + 12x + 5 = 0

3. The attempt at a solution

I'm completely lost here but here's my attempt at a solution - I'm pretty sure that I did it all wrong:

I divided them by 3 and moved the last bit to the other side of the equal sign and made it a minus. I tried using the complete the square method:

x^2+4x=-7/3

After that I have no idea what to do... I don't have a clue how I find the values of p, q and r.
