Answer 2

Answer:

$6x {}^{2} - 14$

Step-by-step explanation:

$p(x) = 2x {}^{3} + 3x {}^{2} + 5x - 7 \\ p( - x) = 2( - x) {}^{3} + 3( - x) {}^{2} + \\ 5( - x) - 7 \\ = - 2x {}^{3} + 3x {}^{2} - 5x - 7$

$p(x) + p( - x) =$

$2x {}^{3} + 3x {}^{2} + 5x - 7 + ( - 2x {}^{3} ) + 3x {}^{2} - 5x - 7$

$6x {}^{2} - 14$
