(!) Use grouping symbols, parentheses to separate numerator and denominator.
(!) Algebra is not formal written English; do not capitalize variable when it is first character on a new line, unless the capitalized form IS the variable assigned or expected.
(!) The site's rendering tag is triple left and triple right curly braces.

Your rational expression in pure text form:
(x^2+7x-18)/(x^2-11x+18)

Your expression inside the rendering tag:

The values of x which must be EXCLUDED are any (two specific ones) which make the denominator 0. Your denominator is factorable:

since this is the denominator,
and .
