Try another version of this question Simplify the following expression.
Box 1: Enter your answer as an expression. Example: 3x^2+1, x/5, (a+b)/c
To simplify the expression `(x+3)/(x^2-4x-21)`, first identify that the denominator can be factored based on the coefficients provided. After factoring the denominator, check if any terms in the numerator can cancel out similar terms in the denominator. This process will involve recognizing common factors between the numerator and the denominator, simplifying the expression to its most reduced form.
Be sure your variables match those in the question `1/(x-7)`
