Below are sample questions representative of the exercises included on this worksheet and related ALG2.11 Error Analysis and Solution Verification skill assessments:

Problem 1Difficulty: Mastery
Three students analyze sqrt(x) = x. Student A says x = 0 and x = 1 are both solutions. Student B says x = 1 only. Student C says x = 0 only. Who is correct?
AStudent A
BStudent B
CStudent C
DNone of the students
Solution & Explanation:Checking x = 0 gives 0 = 0, and checking x = 1 gives 1 = 1. Both values satisfy the original equation.
Problem 2Difficulty: Mastery
The equation (x2 - 9)/(x - 3) = x + 3 simplifies to an identity for allowed x-values. What value must still be excluded from the solution set?
Solution & Explanation:Factoring gives (x - 3)(x + 3)/(x - 3) = x + 3, which is true for x ≠ 3. The original denominator shows that x = 3 must be excluded.
Problem 3Difficulty: Mastery
A student claims x = 1 solves 3/(x - 1) = 3 because 3/0 is 3. Which response is correct?
AThe claim is correct because the numerator matches the right side.
BThe claim is wrong because division by 0 is undefined, so x = 1 cannot be a solution.
CThe claim is correct only if x is positive.
DThe claim is wrong because the denominator should be 3.
Solution & Explanation:A denominator of 0 makes the expression undefined. Since x = 1 causes division by 0, it must be rejected.
