Chapter 6 vocab. rational expressions

Rational Expression This can be written as the quotient of P/Q of two polynomials P and Q as long as Q is not 0
Opposites The expression ( x - 8) and (8 - x) are an example of this.
Expression This is written without an equal sign.
Equation This is written with an equal sign
Directly This is the relationship between y and x in the equation y = kx
Constant of Variation The value of k in the equation y = kx
Undefined Is a result when dividing by zero
Long Division To divide a polynomial by a polynomial other than a monomial and can be used when dividing by (3x - 1) as an example.
Inversely In the equation y = k/x, y is said to vary this way with x.
Domain This can be written in the form { x l x is a real number and x is not equal to the number(s) which would make the denominator zero.
Complex Fraction A rational expression whose numerator, denominator, or both contain one or more rational expressions.
Least Common Denominator The _____________ of a list of rational expressions is a polynomial of least degree whose factors include the denominator factors in the list.
Jointly In the equation y = kHz, y varies this way as x and z.
Extraneous Solution It is a proposed solution that makes the denominator zero or does not work in the original equation.
Simplified Reducing to the smallest terms.
