Answer 1

first we put values and divide given question

and open brackets and solve it....

hope it helps..

Answer 2

Step-by-step explanation:

Here

x³ + 4 - x - 2

x³ - x + 2

than,

by synthetic division,

factor of 2 = 1 , 2

means,

( x - 1) is factor of x³ - x + 2

than,

1 l x³ - x + 2 l

so,

n(Q) = x³ + x²
