Question

use the factor theorem to determine whether x minus 1 is a factor of 8 x to the power 4 + 12 x cube minus 18 x + 14

Answer 1

put x= 1 in polynomial..check if u get 0 then it's factor.. otherwise not a factor

Answer 2

x-1=0
x=0+1=1
put the value 1 for x
8(1)power 4 +12(1)cube -18(1)+14
8(1)+12(1)-18+14
8+12-18+14
20-4=16
so,x-1 is not the factor of the equation
hope it will u...
