Study Notes
Multiplying Binomials
- Identifying patterns makes multiplying binomials easier.
- Key formulas include:
- Sum and Difference Formula: (a + b)(a - b) = a² - b²
- Binomial Squared: (a + b)² = a² + 2ab + b²
- Binomial Cubed: (a + b)³ = a³ + 3a²b + 3ab² + b³
Quadratic Formula
- A reliable method to find solutions for quadratic equations.
- Four methods: factoring, completing the square, guessing, and the quadratic formula.
- The quadratic formula is always applicable.
Rules for Radicals
- Understanding equivalences simplifies working with algebraic radicals.
- Key formulas enable easy calculation of roots of products or quotients and fractional exponents.
- Ensure factors a and b are positive for valid results.
Laws of Logarithms
- Logarithmic properties facilitate addition instead of multiplication.
- Important logarithmic concepts include:
- Logarithm of a product
- Logarithm of a quotient
- Logarithm of a power
- Logarithm of a reciprocal
- Logarithm of base and log of 1
Standard Equations of Algebraic Conics
- Conics arise from slicing a cone with a plane.
- Common conic equations include those for circles, ellipses, parabolas, and hyperbolas.
Cramer's Rule
- Developed by Gabriel Cramer for solving systems of two linear equations.
- Utilizes determinants associated with square matrices for solutions.
Sums of Sequences
- Algebraic techniques provide efficient methods for calculating the sums of sequences.
- The formulas apply to integers, squares, cubes, and terms in arithmetic or geometric sequences.
Permutations and Combinations
- Permutations count subsets where order matters.
- Combinations count subsets where order does not matter.
- Essential for working with larger sets in algebraic contexts.
