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.
