# Math Help - What else can I do?

1. ## What else can I do?

$
16x^3+16x^2+3x
$

$
x(16x^2+16x+3)
$

What else can I do?

2. $
16x^3+16x^2+3x
$

$
x(16x^2+16x+3)
$

$
x [(4x)^2+16x+3]
$

I have to factor it completely. Anything idea?

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

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

4. 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.

$
16x^3+16x^2+3x
$

$
16x^3+12x^2+4x^2+3x
$

$
4x^2(4x+3)+x(4x+3)
$

$
(4x^2+x)(4x+3)
$
