The polynomial which must be added to 3x² +4x + 7 to obtain a sum of 0 is; -3x² -4x +7.

Let the polynomial which must be added to 3x² +4x + 7 to obtain a sum of 0 be represented by P.

In essence;

  • P + 3x² +4x + 7 = 0.

By subtracting 3x² +4x + 7 from both sides of the equation to obtain the value of P; we have;

  • P = 0 -3x² -4x +7.

Ultimately, P = -3x² -4x +7.
