Answer:
Step-by-step explanation:
The most common way to solve for the roots of a polynomial is to use the Quadratic formula, which will return us with two values of x that make the equation equal 0.
...however, this form of the equation is already in root form. If we multiplied these two terms, we'd get 
, and when we factor that, we'd get -13 and 21.
Roots are usually written in the form 
, where the zeroes will be the value of x that makes each binomial equal 0 - aka, the opposite of a and b.
The opposite of 13 is -13, and the opposite of -21 is 21.
Therefore, the solutions of this equation are -13 and 21.

Answer:
43-5= 38 (subtract the y-intercept from the last number to see how many stamps were sold over the past two months)
38/2= 19 (the number of stamps sold over 2 months divided by how many months it took for those stamps to be sold)
19 is what goes in the box
