CPM Homework Help : AC Problem 2-151

Look back at the expressions in problem 2-150 that are not equivalent. Are there any values of the variables that would make them equal? Justify your reasoning.

Hint:

For parts (d) and (f) try setting the expressions or equations equal to each other, then simplify, and explain the meaning of the results.

Answer:

In part (d), the values $a = 0$ or $b = 0$ would make the two expressions equal.

More Help:

In part (e), x ≠ 0 because it is not in the denominator.

Answer 2:

$x = 1$ will make the expressions equal.
