Question

can i ask if we are arranging the algebraic expressions in a standard form will it change its sign?

Answer 1

for an instance \[4-2x^3+3x\]

Answer 2

it wont
like the example you've given above it will be
\[-2x^3+3x+4\]

Answer 3

If, when arranging something in standard form you switch a sign, inadvertently you switch the entire equation. If it's positive, it stays positive. Negative, negative, unless you multiply or divide by a negative.
