Expert Answer
first split the product of the constant term and the coefficient of x squared in big factors.
If the factors that you get don't add up to the coeficient of the middle term then go for the prime factors.
In this case
-1*(-306)=306=9*34(this does not work out, so adjust these factors again)
=18*17(now, this does work, so split the middle term as 35x=18x+17x)
If product is positive it shows that both numbers must be of the same sign, since the middle term coef is +, so both the numbers have to be positive.)
