2A. Radical C. Binomial B. Relational D. Rational A _____________ expression is an expression that can be written as a ratio of two polynomials.A. RadicalC. BinomialB. RelationalD. Rational
3Simplifying a Rational Expression Finding the excluded values. (What values of x make the rational expression undefined?)A rational expression is undefined when the value of x causes the denominator to equal zero.The expression is undefined when x = 3Set the denominator equal to zero and solve for x
4Find the excluded value of the expression: A. (x-3)(x+5)C. (x+5)(x-3)B. X = 3, -5D. X = -3, 5
5Simplify the expression by dividing out the common monomials Factor numerator and denominator completely, then divide out common factors.
