$color(maroon)(=> -x^4 + 5x^3 + 99x^2 + 351x + 378$ is the standard form.

$(x+3)^3 * (14-x)$

$=> (x^3 + 27 + 9x^2 + 27x) * (14-x)$

$=> 14x^3 + 378 + 126x^2 + 378x - x^4 - 27x - 9x^3 - 27x^2$

$color(maroon)(=> -x^4 + 5x^3 + 99x^2 + 351x + 378$ is the standard form.

What is the standard form of y= (x+3)^3(14-x)y= (x+3)^3(14-x)?
