Question

the product of two expressions is x^5+x^4+x^3-x^2-x-1.If one of them is x^2+x+1,find the other​

Answer 1

Step-by-step explanation:

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. 

Answer 2

Answer:

$\bold\red{ \: AnswER \: }$

Total area of the plot = 6000 sq. m

Area of plot allowed for construction = 4500 sq. m

So, area of plot left = (6000 – 4500) sq. m

= 1500

Thus, area of plot left in percentage = 1500 / 6000 × 100

= 150 / 6

We get,

= 25%

Therefore, 25% of plot is left without construction
