Types of Equations We Solve

Linear Equations

One variable, first degree
Form: ax + b = c
Always one solution

Quadratic Equations

Form: ax² + bx + c = 0
0, 1, or 2 solutions

Systems of Equations

Multiple variables
2+ equations
Find all unknowns

Solving Strategies by Equation Type

Linear Equations Strategy

  1. Distribute and remove parentheses
  2. Combine like terms on each side
  3. Move variables to one side, constants to other
  4. Isolate the variable by division
  5. Verify solution in original equation

Quadratic Equations Strategy

  1. Write in standard form: ax² + bx + c = 0
  2. Try factoring first (if coefficients are simple)
  3. Use quadratic formula if factoring fails
  4. Calculate discriminant to determine solution type
  5. Simplify and verify both solutions

Systems of Equations Strategy

  1. Choose method: substitution vs elimination
  2. For substitution: solve one equation for one variable
  3. For elimination: multiply to create opposite coefficients
  4. Solve for first variable, then back-substitute
  5. Check solution in both original equations

Common Algebra Patterns

Factoring Patterns

  • a² - b² = (a+b)(a-b)
  • a² + 2ab + b² = (a+b)²
  • a² - 2ab + b² = (a-b)²
  • a³ + b³ = (a+b)(a²-ab+b²)
  • a³ - b³ = (a-b)(a²+ab+b²)

Solution Patterns

  • No solution: 0x = 5 (contradiction)
  • Infinite solutions: 0x = 0 (identity)
  • Integer solutions: Often from factoring
  • Rational solutions: Fractions common
  • Irrational solutions: From √ in quadratic

Common Mistakes and How to Avoid Them

Sign errors: When moving terms across equals sign, change the sign. Moving +5 to other side becomes -5.
Distribution errors: Distribute to all terms inside parentheses. 2(x + 3) = 2x + 6, not 2x + 3.
Division by zero: Check that you're not dividing by zero or by an expression that could equal zero.
Losing solutions: When squaring both sides or canceling terms, you might lose or gain solutions. Always verify.

Frequently Asked Questions

How do I solve a linear equation step by step?

To solve a linear equation: 1) Simplify both sides by combining like terms, 2) Move all variable terms to one side and constants to the other, 3) Divide both sides by the coefficient of the variable, 4) Check your answer by substituting back. Our calculator shows each step with explanations.

What is the quadratic formula and when do I use it?

The quadratic formula is x = (-b ± √(b²-4ac)) / 2a, used to solve ax² + bx + c = 0. Use it when factoring is difficult or impossible. The discriminant (b²-4ac) tells you: positive = two real solutions, zero = one solution, negative = complex solutions.

How do I solve a system of equations?

Common methods: 1) Substitution - solve one equation for a variable and substitute into the other, 2) Elimination - add/subtract equations to eliminate a variable, 3) Graphing - find the intersection point. Our calculator uses the most efficient method and shows the work.

What types of equations can this calculator solve?

Currently supports: Linear equations (ax + b = c), Quadratic equations (ax² + bx + c = 0), Systems of two linear equations. Coming soon: Polynomial equations, Rational equations, Exponential and logarithmic equations, Inequalities.

How do I input equations correctly?

Use standard notation: multiplication is implicit (2x not 2*x), exponents use ^ symbol (x^2 for x²), include equals sign, spaces are optional. Examples: '2x + 5 = 13', 'x^2 - 4x + 3 = 0', '3(x-2) = 15'. The calculator handles most common formats.

What do complex solutions mean?

Complex solutions occur when a quadratic equation has no real solutions (negative discriminant). They're written as a ± bi where 'i' is the imaginary unit (√-1). These solutions come in conjugate pairs and are important in advanced mathematics, physics, and engineering.

How can I check if my answer is correct?

Always verify by substituting your solution back into the original equation. Both sides should equal. For example, if x = 3 solves 2x + 4 = 10, check: 2(3) + 4 = 6 + 4 = 10 ✓. Our calculator includes verification in the step-by-step solution.
