Answer:
72x² - 204x + 144
Step-by-step explanation:
When two linear functions are combined with addition and then by multiplication, Â 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 Â and (x-3)=0
combining the two by multiplication will form
(x+2) (x-3) = x²-1x-6
x²-1x-6=0
