Question

use synthetic division to find the function values
f(x)=x^4-16 f(1-sqrt10)

Answer 1

i dont know how to continue the synthetic division after the first time you multiply it by itself\[its looks like f(x)= x ^{4}- 16 and the f(1-\sqrt{10)}\]

Answer 2

Synthetic division works with the coeffecients of your function. From your equation it simply looks like you need to plug [1-sqrt(10)] into your function. I'm not seeing a division problem. Maybe draw it or upload a photo of the original problem
