hi guys!

Question

I was wondering how to do x6-18x2+8 divided by factor x2-4

I normally use synethetic division what else easier method should i use?

Answer 1

since x^2 - 4 = (x+2)(x-2) use synthetic division twice, it works out

make sure you allow for the missing terms in the line-up

1 0 0 0-18 0 8

I ended up with x^4 + 4x^2 - 2

Answer 2

thank you so much!

also for x3+1 what is the factor??

is it isquareroot1
