# What is the standard form of a polynomial (5x - 2 + 3x^2) + (4x + 3)?

$3 {x}^{2}$ + 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 + $3 {x}^{2}$ = 0. Then rearrange them into the “standard form”:
$3 {x}^{2}$ + 9x + 1 = 0.
