Question

find remainder if (x-1) is a factor of xsquare -4x+8

Answer 1

Answer:

remainder=5

Step-by-step explanation:

x-1=0

x=1

x2-4x+8

(1)2-4(1)+8

1-4+8

-3+8

5

Answer 2

Answer:

5

Step-by-step explanation:

since x-1 is a factor of x^2-4x+8

let g(x)=x-1

0=x-1

thus x=1

now, f(x)=x^2-4x+8

f(1)=1^2-4*1+8

=1-4+8

=5

therefore 5 is the remainder when x^2-4x+8 is divided by x-1.
