16x^3+16x^2+3x<br />

    <br />
x(16x^2+16x+3)<br />

    <br />
x [(4x)^2+16x+3]<br />

    I have to factor it completely. Anything idea?

     16x^2 + 16x + 3 this can be factored into


     ( 4x+ 1) ( 4x +3)

    No, Tweety.
    You must have made a mistake, since it is 16x^3, not 16x^2. But anyway you helped me to find the right answer. Thanks.


    <br />
16x^3+16x^2+3x<br />

    <br />
16x^3+12x^2+4x^2+3x<br />

    <br />
4x^2(4x+3)+x(4x+3)<br />

    <br />
(4x^2+x)(4x+3)<br />
