Two linear functions are combined with addition, and then the same two linear functions are combined by multiplication.

Which functions could be the result of the combinations? Select two options.

16x - 12

17x - 12

72x? - 96x

72x2 - 108

72x2 - 204x + 144

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
