Algebra 2 Quiz
15 questions · free · new questions every attempt · Updated September 26, 2026
Algebra 2 deepens everything from Algebra 1 and adds logarithms, sequences and a fuller study of quadratics. The questions in this quiz focus on the calculations that appear most often on chapter tests and end-of-year exams, and each one explains the reasoning behind the answer.
What this quiz covers
- Solving quadratic equations by factoring
- Computing the discriminant
- Finding the vertex of a parabola
- Evaluating logarithms and using the product rule
- Arithmetic and geometric sequences
- Exponent laws and factoring
How to prepare
Use the discriminant b² − 4ac to know what kind of roots to expect before you solve. Learn the log rules as three simple statements: product becomes a sum, quotient becomes a difference, and a power comes down as a multiplier. For sequences, decide first whether the pattern adds or multiplies.
Sample questions with answers
These five questions show the style. Your quiz above will have different numbers each time.
- Solve x² + 1x − 6 = 0.
Show answer
x = -3 or x = 2. Factor as (x − 2)(x + 3) = 0, so x = 2 or x = -3.
- Find the discriminant of 2x² − 3x − 4.
Show answer
41. b² − 4ac = -3² − 4(2)(-4) = 41.
- What is the x-coordinate of the vertex of y = 2x² + 12x + 1?
Show answer
-3. x = −b ÷ 2a = -12 ÷ 4 = -3.
- Evaluate log₅(125).
Show answer
3. 5³ = 125, so the logarithm is 3.
- Which expression equals log(9 × 9)?
Show answer
log(9) + log(9). The log of a product is the sum of the logs.
Frequently asked questions
What is the difference between Algebra 1 and 2?
Algebra 2 covers polynomials of higher degree, exponential and logarithmic functions, sequences, complex numbers and more advanced systems.
What is a discriminant?
It is b² − 4ac and tells you whether a quadratic has two real, one repeated or two complex roots. The quadratic solver shows it.
How should I study logarithms?
Start by translating: log₂(8) = 3 means 2³ = 8. Then practise with the logarithm calculator.
