Simplifying Rational-Fractional Expressions
Problem: Simplify in the simplest form (x2+5x+6)/(x2-4)
Solution First, factorize each of the two polynomial, cancel out the common factor in both
Solution Factors of (x2+5x+6) = (x+2)(x+3);Factors of (x2-4) = (x+2)(x-2)
Solution (x+2) is common in both cancel it. (x+3)/(x-2) is left out and is answer.
Solution Answer: (x+3)/(x-2)
