STUDY SKILLS
We introduced study cards on page 48.Another type of study card follows.
Practice Quiz Cards
Write a problem with direction words (like solve, simplify) on the front of the card, and
work the problem on the back. Make one for each type of problem you learn.

True
Any real number will work , so the
solution set is {all real numbers} (not just {0}).When both sides
of an equation are
the same, it is called
an identity.p. 103
