Answer:
72x² - 204x + 144
Step-by-step explanation:
When two linear functions are combined with addition and then by multiplication, quadratic equation is formed.This is an equation of one degree where it contains at least one term that is squared.
example, two linear functions can be;
(x+2)=0 and (x-3)=0
combining the two by multiplication will form
(x+2) (x-3) = x²-1x-6
x²-1x-6=0
