I think we want the numbers that are in place of a, b, and c, when the equations are in this form:

ax2 + bx + c  =  0

 

1.

 

3x2 - 2x - 16  =  0

a = 3 ,     b = -2 ,     c = -16

 

 

2.

 

3x - 16  =  0                           This is the same as...

0x2 + 3x - 16  =  0

a = 0 ,     b = 3 ,     c = -16

 

 

3.

 

51x2 - 56x  =  0                      This is the same as...

51x2 - 56x + 0  =  0

a = 51 ,     b = -56 ,     c = 0
