Question

Which of the following is equal to the rational expression when x*-2 or 3?

Answer 1

The value of the expression in the simplified form is f(x) = x+3/x-3

Rational expression

Rational expressions are expressions written as a ratio of two integers or expressions.

Given the rational expression below;

f(x) = x²+5x+6/x²-x-6

Factorize the numerator and denominator

f(x) = x²+3x+2x+6/x²-3x+2x-6

f(x) = x(x+3)+2(x+3)/x(x-3)+2(x-3)

f(x) = (x+3)(x+2)/(x+2)(x-3)

f(x) = x+3/x-3

Hence the value of the expression in the simplified form is f(x) = x+3/x-3
