i need the questions answered for 4x+12=0

Question

What is the highest exponent of the variable ?

 

what does the exponent tell us about the solution of the equation?

 

Why is a≠0?

Answer 1

The highest exponent of the variable is 1.

 

4x¹ + 12x⁰ = 0

 

 

being that x¹ is the same as x, and x⁰ is the same as 1.

 

 

The exponent tells us the number of x-intercepts we will have.  x-intercepts are points on the x-axis and contains the coordinate point  (x , 0).

 

 

 

Answer 2

There is a problem with the question. There is no "a".
