12x^2 +4x=4x(3x+1)

For factoring you should first find the same thing between two parts and divide them to it.The exponent of first part is the least exponent in equation.The answer will have two parts,one of them is common part and other one is rest of answer.If you multiply these parts again you should find the same result as first equation if not your answer is incorrect.In below there is an example for bigger exponents:

81x^4+ 27x^3+9x^2=9x^2(9x^2+3x+1)
