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. Homework Help ✎
For parts (d) and (f) try setting the expressions or equations equal to each other, then simplify, and explain the meaning of the results.
In part (d), the values a = 0 or b = 0 would make the two expressions equal.
In part (e), x ≠ 0 because it is not in the denominator.
x = 1 will make the expressions equal.
