a = -1
b = -9
c = -1/8
Step-by-step explanation:
The given polynomial:

Rewritting in the form:

where a is the coefficient of x²
b is the coefficient of x
c is the constant (only number)
Comparing both equation:
ax² = -x²
If you divide through by x², a = -1
a = -1
bx = -9x
if you divide through by x, b = -9
b = -9
c = -1/8
