How do you factor #36y^2+12y-35#?
we split the product of these two i.e.
The only two parts whose product is
Note - (1) If signs are same select two numbers whose product is product of constant term and coefficient of highest power and sum is equal to middle term.
(2) In case one finds difficult to get two factors whose sum or difference is equal to middle term, try out starting from
Here you find a difference (or sum in case you need that) at a very late stage and hence takes time. But if product is large and sum/difference is much smaller, one can try starting with a factor, which is close to square root of the product. Here product was
