1. If the polynomial y3 - 5y2 + 7y + m is divided by y + 2 and the remainder is 50 then find
the value of m.
2. IF (x31+ 31) is divided by (x + 1) then find the remainder.
3. Show that m-1 is a factor of mal - 1 and m-2-1​

Answer 1

Step-by-step explanation:

put y=-2

f(-2)=50

-8-5(4)+7(-2)+m=50

-8-20-14+m=50

m=50+42=92

2)

put x=-1

(-1)^31+31=-1+31=30. (-1)^odd=-1

remainder=30

3)

put m=1

(1)^-1 -1=1-1=0

similarly

(1)^-2 -1=1-1=0
