Johnny was given this problem to write an equation for: You buy a used car for $6599. Its value decreases by 12% every year. Johnny thinks the equation is y = 6599(0.12)

Explain why Johnny is incorrect.

What is the correct equation to represent the situation to insert an exponent use x.

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
