Junior year can bring demanding courses alongside college planning. Keep the study task specific: identify one misconception, work through an example, and check that you can explain the result before moving to another subject.
Try the worked exampleReturn to the original question
Some algebraic steps produce candidate answers that fail the original equation. Checking those candidates is part of solving. The same care helps in history and English: return to the original source or prompt before deciding your answer is complete.
Does this candidate work in the original equation, and what changed when we squared?

Check solutions after squaring
Solve a square-root equation and reject values that fail the original equation.
Squaring can remove a square root, but it can also lose sign information: 3 and −3 have the same square. A value that solves the squared equation may fail the original one. That value is an extraneous solution, so substitution is part of solving, not an optional extra.
For real-number solutions, the expression inside a square root must be nonnegative. The principal square root itself is also nonnegative. If √(x + 6) equals x, then x must be nonnegative before you even square both sides.
Solve √(x + 6) = x over the real numbers.
- The left side is nonnegative, so require x ≥ 0. Squaring both sides gives x + ².
- Rearrange and factor: x² − x − (x + 2) = 0. The candidates are and x = −2.
- Check the original: √(3 + 6) = 3, but √(−2 + 6) = 2, not −2. Keep and reject x = −2.
Your turn.
Which value solves √(x + 2) = x over the real numbers?
- x = −1 only
- only
- Both x = −1 and
Show the answer and explanation
only
Squaring gives x² − x − (x + 1) = 0. The original equation works at 2 because √. At −1 it says √1 = −1, which is false.

A routine to try next.
- Write down the original question and any restrictions before transforming it.
- Label intermediate results as candidates until you have checked them.
- Explain why each candidate works or fails, then note the error you want to avoid next time.
These public guides and examples are free to read without an account. FutureSteps accounts are for ages 13 and older, with email verification and applicable permission steps. Younger learners can explore these public examples with a grown-up.
Eligible students receive a 90-day homework trial from their signup date, after email verification and required age and permission checks. No invitation is needed. Up to 100 Study requests per day, subject to your weekly allowance and service availability. Longer chats and photos may use more allowance. AI coaching requires a paid upgrade from the start. The homework trial needs no card and never charges automatically.
Grade level does not determine account eligibility. For eligible students, in-app Study includes AI homework help and tutoring; college and career AI coaching is a separate paid feature.
Questions before you begin.
How can I keep schoolwork and college planning separate?
Choose a specific study task for a current course, then keep college comparisons and application preparation in their own planning list. The junior-year college planning checklist linked below offers a separate starting point for those decisions.
How does the in-app learning path build on these examples?
Eligible students choose a supported state, grade and courses. Lessons include explanations, worked examples and quick checks. Students can save Notes, mark their own progress and ask Study about a lesson when they have access. Progress labels reflect the student's selections, not a school grade or a mastery assessment.
Review or look ahead.
