ABCDEFGHIJKLMNOPQRSTUVWXYZ

Cube root

When $n = 3$ in $$a = {b^n}$$.

Coordinates

The numbers in an ordered pair that locate a point on a coordinate system.

Constants

A collection of real numbers used in combination with variables using addition, subtraction, multiplication, and division to create an algebraic expression.

Constant term

The number $a_0$ in a polynomial in $x$.

Consistent system

A system of equations with exactly one solution. The slopes of the lines are not equal.

Conjugates

Two expressions that differ only in sign between the terms. The product of two conjugates is the difference of two squares.

Composite number

Integer greater than 1 with more than two factors.

Complex number

A number of the form $a + bi$ where $a$ and $b$ are real numbers.

Complex fractions

A fraction that has a fraction in its numerator or denominator, or both.

Complex conjugates

Two pairs of complex numbers that differ only in sign between the terms. The product of two complex conjugates is the difference of two squares.

Completing the square

The process of adding $(b/2)^2$, which is the square of half of the coefficient of $x$ in the expression $x^2 + bx$, to the expression. Consequently, $${x^2} + bx + {\left( {\frac{b}{2}} \right)^2} = {\left( {x + \frac{b}{2}} \right)^2}$$.

Commutative property of multiplication

Two real number can be multiplies in either order. $ab = ba$

Two real numbers can be added in either order. $a + b = b + a$

Coefficient

The numerical multiplier of a term.
