Answer:  a = 1, b = 0, c = -36

Step-by-step explanation:

Move everything to one side so zero is on the other side.

Then you have it in the form: ax² + bx + c = 0

x² - 86 = -50

   +50   +50

x² - 36 =  0

Notice that there is no "x" term so its coefficient is zero.

1x² + 0x - 36 = 0

a=1    b=0   c=-36
