${\left(-4\right)}^2+7\cdot -4+12$
Learn how to solve limits by direct substitution problems step by step online. Find the limit of x^2+7x+12 as x approaches -4. Evaluate the limit \lim_{x\to-4}\left(x^2+7x+12\right) by replacing all occurrences of x by -4. Multiply 7 times -4. Subtract the values 12 and -28. Calculate the power {\left(-4\right)}^2.
