Answer 1

Carbon dioxide is a chemical compound composed of one carbon and two oxygen atoms. It is often referred to by its formula CO2. It is present in the Earth's atmosphere at a low concentration and acts as a greenhouse gas. In its solid state, it is called dry ice. It is a major component of the carbon cycle.

Answer 2

$p(x)=x³- 2x²+x+1 \\ \\ p(0) = 0 - 2 \times 0 + 0 + 1 \\ p(0) = 0 - 0 + 0 + 1 \\ p(0) = 1 \\ \\ \\ p( - 1) = { - 1}^{3} - 2 \times { - 1}^{2} + ( - 1) + 1 \\ p( - 1) = - 1 - 2 \times 1 - 1 + 1 \\ p( - 1) = - 1 - 2 \\ p( - 1) = - 3$

Therefore

$p(0) \times p( - 1) = 1 \times - 3 = - 3$

hope it will help u ✨☺️
