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. $ab = ba$
Commutative property of addition
Two real numbers can be added in either order. $a + b = b + a$
Coefficient
The numerical multiplier of a term.
