Divide using synthetic division (a^4+ 8a^3- 6a – 54) % (a +8)

The given polynomial is:
[tex]\frac{a^4+8a^3-6a-54}{a+8}[/tex]Follow the steps below to use the synthetic division method.
Start by writing down the coefficients into an upside-down division box
Since the divisor is a+8, a = -8 is the test zero
