- 3x^2 - 4x - 7

Step-by-step explanation:

Let A should be added in the given polynomial to obtain a sum of zero.

Therefore,

$A + 3 {x}^{2} + 4x + 7= 0 \\ \\ A = 0 - (3 {x}^{2} + 4x + 7 ) \\ \\ A = 0 - 3 {x}^{2} - 4x - 7 \\ \\ A = - 3 {x}^{2} - 4x - 7 \\$

Thus, $- 3 {x}^{2} - 4x - 7$ should be added in the given polynomial to obtain a sum of zero.
