UNKNOWN_123 I think that if you know quadratic factorisation you should not have problems with non-monics...
A non-monic equation is basically just an equation with anything other than a 1 as a coefficient right?
So 2x2 + 5x + 3 = 0 is an example of a non-monic
You just multiply 2x2 and 3, which gets you 6x2
Then you split 5x in a way that the addition remains 5x and the numbers result in 6x2 when multiplied
Which will be 2x2 + 3x + 2x + 3
Then you just factorise
Unless you meant something else and I am completely wrong
