Determine whether each statement in Exercises 43鈥�50 is true or false. $$0 \geq-13$$
Using an example, explain how to factor out the greatest common factor of a polynomial.
$$\text { factor completely.}$$ $$-x^{2}-4 x+5$$
A large number can be put into perspective by comparing it with another number. For example, we put the \(\$ 15.2\) trillion national debt (Example 12 ) and the \(\$ 2.17\) trillion the government collected in taxes (Exercise 115 ) by comparing these numbers to the number of U.S. citizens. For this project, each group member should consult an almanac, a newspaper, or the Internet to find a number greater than one million. Explain to other members of the group the context in which the large number is used. Express the number in scientific notation. Then put the number into perspective by comparing it with another number.
