Question

Find the remainder when x3 + x2 +3x +1 is divided by x-1/2
(By using factor theorem)
​

Answer 1

Step-by-step explanation:

using factory theoram

x-1/2

x=1/2

putting the value in the equation..

(1/2)^3+(1/2)^2+3*1/2+1

1/8+1/4+3/2+1

talking 8 as the LCM

1+2+9+8/8

20/8 =2.5

Answer 2

Answer:

23/8

Step-by-step explanation:

when the expression is decided by 1/2 so the remainder can be find out by putting the value of x in the expression that comes from-

x-1/2 = 0

x = 1/2

put 1/2 in place of x in the expression to get the remainder that is 23/8.
