Question

×^4+2×^3-3×^2+×-1 is divided by ×_2​

Answer 1

Answer:remainder is 21

Step-by-step explanation:

f(x)=×^4+2×^3-3×^2+×-1

g(x)=x-2

By factor theorem,

When f(x) is divided by g(x)=x-a, the remainder is f(a)

Therefore,x will be substituted by 2

f(2)=2^4+2*2^3-3*2^2+2-1

=16+16-12+2-1

=34-13

=21
