Question

Find the remainder when the polynomial f (x) = 2x4 – 6x3 + 2x2 – x + 2 is divided by (x + 1).​

Answer 1

Answer:

-6

Step-by-step explanation:

Divisor= x+1

x=-1

f(-1)=(2×4)-(6×3)+(2×2)-(-1+2)

=8-18+4-1

=-7

Answer 2

Answer:

x=13

Step-by-step explanation:

Remainder:- f(x)=0

x+1=0

x=0-1

x= -1

f(x)= 2x⁴-6x³+2x²-x+2

f(-1)= 2(-1)⁴-6(-1)³+2(-1)²-(-1)+2

f(-1)= 2-(-6)+2+1+2

f(-1)=2+6+2+1+2

f(-1)=13
