Study Notes
Distributive Property
- Represents the method of distributing multiplication over addition: (x(y+z) = xy + xz)
- Essential for simplifying algebraic expressions.
Simplification Techniques
- The expression (xy + xz) simplifies to (x(y + z)), showcasing the distributive property.
- Understanding these simplifications aids in problem-solving and algebraic manipulation.
FOIL Method
- FOIL stands for First, Outer, Inner, Last, used to expand the product of two binomials: ((a+b)(x+y) = ax + ay + bx + by)
- An effective strategy for multiplying binomials.
Quadratic Expansions
- Quadratic Type 1: ((x+a)(x+b) = x^2 + (a+b)x + ab)
- Quadratic Type 2: ((ax+b)(cx+d) = acx^2 + (ad+bc)x + bd)
- Quadratics represent polynomial expressions of the second degree.
Perfect Squares
- Trinomial Perfect Square: The formula ((x+y)^2 = x^2 + 2xy + y^2) indicates how to expand the square of a binomial.
- Another form: ((x-y)^2 = x^2 - 2xy + y^2) accounts for subtraction.
Difference of Squares
- The formula ((x+y)(x-y) = x^2 - y^2) demonstrates how the product of a sum and difference results in a difference of squares.
- This is a useful factorization technique.
Cubes of Binomials
- Cube Formula for Sums: ((x+y)^3 = x^3 + 3x^2y + 3xy^2 + y^3)
- Cube Formula for Differences: ((x-y)^3 = x^3 - 3x^2y + 3xy^2 - y^3)
Sum and Difference of Cubes
- Sum of Two Cubes: (x^3+y^3 = (x+y)(x^2 - xy + y^2)) is crucial for factoring cubic expressions.
- Difference of Two Cubes: (x^3-y^3 = (x-y)(x^2 + xy + y^2)) provides another factorization method.
Notations and Simplifications
- Proficiency in recognizing and applying these formulas fosters stronger algebra skills.
- Simplifying outcomes like (x^3+y^3) to ((x+y)(x^2-xy+y^2)) reinforces understanding of polynomial identities.
