1 answer:

8 0

Answer:

3x³ - 12x + 4

Step-by-step explanation:

The opposite of a polynomial P is -P.

You find the opposite of P by multiplying it by -1.

P = -3x³ + 12x - 4

-P = (-1)( -3x³ + 12x - 4) Distribute -1 to each term

= (-1)(-3x³) + (-1)(12x) - (-1)(4) Multiply each coefficient by -1

= 3x³ + (-12)x - (-4)

= 3x³ - 12x + 4
