Common Algebra Problems

See how to solve typical algebra problems with your TI-84

Solving Quadratic Equations

Problem: Solve x² - 7x + 12 = 0

Method 1: Factoring
• Factor: (x-3)(x-4) = 0
• Solutions: x = 3, x = 4

Method 2: Quadratic Formula
• Use: (-b ± √(b²-4ac)) / 2a

✓ Answer: x = 3, x = 4

Systems of Linear Equations

Problem: Solve the system
2x + 3y = 7
x - y = 1

TI-84 Method:
• Enter as matrix equation
• Use rref([A|B]) command
• Read solution from result

✓ Answer: x = 2, y = 1

Polynomial Multiplication

Problem: Expand (x+2)(x²-3x+1)

TI-84 Method:
• Use expand() function
• Or multiply term by term
• Distribute and combine like terms

✓ Answer: x³ - x² - 5x + 2

Simplifying Rational Expressions

Problem: Simplify (x²-4)/(x²+4x+4)

Steps:
• Factor numerator: (x-2)(x+2)
• Factor denominator: (x+2)²
• Cancel common factors

✓ Answer: (x-2)/(x+2)

Finding Vertex of Parabola

Problem: Find vertex of y = x² - 4x + 3

TI-84 Method:
• Graph the function
• Use CALC → Minimum
• Or complete the square

✓ Answer: Vertex at (2, -1)

Solving Inequalities

Problem: Solve x² - 5x + 6 > 0

Method:
• Factor: (x-2)(x-3) > 0
• Find sign of each factor
• Test intervals

✓ Answer: x < 2 or x > 3
