a = -1
b = -9
c = -1/8
Explanation:
The given polynomial:
[tex]\frac{-1}{8}\text{ - 9x }-x^2[/tex]Rewritting in the form:
[tex]\begin{gathered} ax^2\text{ + bx + c} \\ -x^2\text{ - 9x -}\frac{1}{8} \end{gathered}[/tex]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
