Study Notes

Real Numbers

Include both rational (fractions, integers) and irrational numbers (non-repeating decimals).

Opposites

Defined as numbers equidistant from zero but located on opposite sides of the number line.

Absolute Value

Represents the distance from zero on the number line, always positive.

Algebraic Expression

Combinations of numbers, variables, and operational symbols (sum, difference, product, quotient).

Commutative Property

In both addition and multiplication, order of operations does not affect the result.

Associative Property

For addition and multiplication, how numbers are grouped does not change the outcome.

Distributive Property

Multiplication can be distributed across addition, facilitating simplification of expressions.

Conjunction

A logical statement formed by combining two statements with "and".

Disjunction

A logical statement formed by combining two statements with "or".

Coordinate

An ordered pair (x, y) representing a specific point in the xy-coordinate plane.

Origin

The point of intersection for the x and y axes, denoted as (0,0).

Quadrant

The coordinate plane is divided into four regions by the intersecting axes.

Slope of a Line

Measures how steep a line is, calculated as the ratio of vertical change to horizontal change.

Standard Form

Represents a linear equation in the form Ax + By = C.

Point-Slope Form

Format for linear equations expressed as y - Y = M(x - X), capturing slope and a point on the line.

Coefficient

The numerical factor that multiplies a variable in an algebraic term.

Slope-Intercept Form

Linear equations expressed as y = mx + b, where m is the slope and b is the y-intercept.

Monomial

A single term that can be a constant, variable, or a product of constants and variables.

Degree of a Polynomial

Identifies the highest degree among the terms in a polynomial after simplification.

Function

A relation where each input has a unique output, ensuring no repeated first coordinates.

Relation

A set of ordered pairs that can represent various mathematical relationships.

Prime Number

An integer greater than one with no divisors other than one and itself.

Prime Factorization

The process of breaking down a positive integer into a product of prime numbers.

Rational Expression

An algebraic expression that can be simplified into a quotient of two polynomials.

Extraneous Root

A solution to a modified equation that does not satisfy the original equation.

Like Radicals

Radicals that share the same index and radicand, permitting direct addition or subtraction.

Rational Number

Any number that can be expressed as a fraction or ratio of two integers.

Irrational Number

A number that cannot be expressed as a simple fraction, characterized by infinitely non-repeating decimals.

Pure Imaginary Number

A complex number exclusively of the form bi, where b is a real number.

Complex Number

A number expressed in the form a + bi, combining a real part (a) and an imaginary part (bi).

Quadratic Formula

The solution for quadratic equations in the standard form ax² + bx + c = 0.

Discriminant

Calculated as b² - 4ac, helps determine the nature and number of roots of a quadratic equation.

Parabola

The graph representation of a quadratic equation characterized by the form y - k = a(x - h)².

Vertex

The highest or lowest point of a parabola, identified as the point (h, k).

Dividend

The quantity that is being divided in a division operation.

Divisor

The quantity by which another quantity is divided during the division process.

Division Algorithm

Describes the relationship: Dividend = Quotient × Divisor + Remainder.
