For factoring trinomials, it's largely guess and check. However, you'll want to notice that $$16x^2=(4x)^2$$ and $$36y^2=(6y)^2$$. A natural first choice for a possible factorization would then be$(4x+6y)^2$As it turns out, we we FOIL this again, we get $16x^2+24xy+24xy+36y^2=16x^2+48xy+36y^2$So we know we've found the correct answer.
