I don't know what this means. However
if you want to solve it without using the quadratic formula or the completing the sqares method you will need to factorise it!

To factorise 3x^2 + 20x + 12
you need to find 2 numbers that multiply to 3*12=+36
and add to +20
You get back to me with those numbers and then we will continue.
