I'm factoring some equations and the way I do it seems correct and Wolfram often lists my way of factoring it but it's like the 5th or 6th one down. Just wondering if it's like fractions where the best answer is the lowest the fraction can be reduced to. For example I say that: [tex]3a+6a^2+15a^3 = 3a(1+2a+5a^2)[/tex] Wolfram doesn't list my way of factoring it when I input the equation to be factored, but I know it's correct because when I input my factored form instead of the original problem, it lists the original problem as a solution. Any particular way to be factoring these? Like highest exponenets first, not using 1 ect?
