Question

Find the product of x3 – 1 and x3 + 1. Hence divide the result by x2 + x + 1​

Answer 1

Answer:

Let the other equation  be y

According to question

y×(x2+x+1)=x5+x3+x 

∵y=x2+x+1x5+x3+x    

Now  By using the long division method 

As shown in the figure 

hence on solving the equation the other expression is x3−x2+x.
