Algebra Solving Tools
Linear Equation Solver
Solve ax + b = c.
Quadratic Solver
Solve ax² + bx + c = 0.
Two-Equation System
Solve a₁x + b₁y = c₁ and a₂x + b₂y = c₂.
Formula Used
- Slope: m = (y₂ - y₁)/(x₂ - x₁)
- Slope-intercept: y = mx + b
- Point-slope: y - y₁ = m(x - x₁)
- Standard line: Ax + By = C
- Quadratic: x = (-b ± √(b² - 4ac))/(2a)
- Discriminant: Δ = b² - 4ac
- Vertex: x = -b/(2a)
- Difference of squares: a² - b² = (a-b)(a+b)
- Arithmetic sequence: aₙ = a₁ + (n-1)d
- Geometric sequence: aₙ = a₁rⁿ⁻¹
- Exponential growth: A = P(1+r)ᵗ
- Percent change: change/original × 100

Frequently Asked Questions
Is this an official FSA test?
No. It is an independent Algebra 1 practice tool. Questions are original and designed for skill review.
What does the calculator portion include?
It includes equations, functions, graphs, statistics, and modeling. Built-in tools support common Algebra 1 calculations.
Can I practice one topic?
Yes. Clear all topics, then select one category. The test uses available questions from that category.
How does study mode work?
Study mode checks each answer immediately. It also displays explanations and formulas. Exam mode waits until final submission.
What happens in adaptive mode?
Adaptive mode mixes difficulty based on recent accuracy. Strong performance increases harder-question selection. Misses increase foundational review.
Are equivalent numeric answers accepted?
Yes. Numeric responses use a small tolerance. Decimal precision can be adjusted before starting.
Can I save my progress?
Completed attempts are stored in your browser. The dashboard tracks scores and topic performance. Clearing browser data removes saved records.
Can I export my results?
Yes. Download a CSV, copy the summary, or print as PDF. These options appear after submission.
Does the graphing tool solve every function?
No. It graphs common Algebra 1 expressions using x. Invalid expressions display an error message.
