Learn how to solve limits by direct substitution problems step by step online. Find the limit of (x^2+x+-12)/(x-3) as x approaches 3. Factor the trinomial x^2+x-12 finding two numbers that multiply to form -12 and added form 1. Rewrite the polynomial as the product of two binomials consisting of the sum of the variable and the found values. Simplifying. Evaluate the limit \lim_{x\to3}\left(x+4\right) by replacing all occurrences of x by 3.
