I'm not sure how to factor 3x^312x^2+3x. I tried separatring the 3x so that 3x(x+1)(x4, but I got 3x^3+12x^23x^2+12x. Can you show me where I went wrong and how to properly factor this? Is there a general rule or tip for this

help...solving a polynomial....algebra
solve this please....help me....12x(squared)+7x10 Do you wish to factor this trinomial? If so, the factors are: (4x + 5)(3x  2) You can use the FOIL method to check. If this is supposed to be an equation: 12x^2 + 7x  10 = 0
