Answer
$-18x^2+228x+2300$
Work Step by Step
This is the problem we need to solve:
$(-11x^2+133x+1200)+(-7x^2+95x+1100)$
We need to find how many students there are in total at both schools. To do this, we will add both polynomials. This will help us find the total population in both high schools.
We need to add like terms, which are terms which have the same variables.
$-18x^2+228x+2300$
That's your answer!
