$3x^2$ + 9x + 1 = 0.

The “standard form” is an equation with each variable arranged in decreasing order of exponent and equated to zero. E.g. $x^2$ + x + 1 = 0

In this case, we first must combine all of the terms: 9x + 1 + $3x^2$ = 0. Then rearrange them into the “standard form”:
$3x^2$ + 9x + 1 = 0.
