Two or zero expresses the possible number of positive real  solutions for the given polynomial equation.

Answer: Option D

<u>Step-by-step explanation:</u>

Given equation:

        x^{3}-4 x^{2}-7 x+28=0

First, we put hit and trial method to find out the one solution. So, if we put x=4 then the above expression will become zero.  We can also write the above expression as  

      (x-4) \times\left(x^{2}-7\right)=0

We know the formula, a^{2}-b^{2}=(a+b)(a-b), make use of this, we get

   (x-4) \times(x-\sqrt{7}) \times(x+\sqrt{7})=0

So, x=4, \sqrt{7},-\sqrt{7}

Hence, from the above expression, we have three values of x as x= 4, 2.64 and -2.64

Problem:
 The area of the patio of a relative's house is 20 square meters.
 The width of the patio is 2 meters.
 What is the length of the patio?
 Solution:
 
The area is:
 A = (w) * (l)
 Where,
 w: width
 l: long
 Clearing l we have:
 l = A / w
 Substituting values:
 l = 20/2
 l = 10 meters

Let C = the Chinese books.
Let E = the English language books.

C = 4/5 E

E - 300 = C - 180 Notice how you get this equation. You take 300 away from the English books and 180 from the Chinese and according to the question, you get an equal number of both. Put c = 4/5E into the second equation.

E - 300 = 4/5 E - 180 Add 300 to both sides.
E = 4/5 E - 180 + 300
E = 4/5 E + 120 Now subtract 4/5 E from both sidies.
E - 4/5 E = 120
1/5 E = 120 Now multiply by 5
E = 120 * 5
E = 600

So the number of books are
600 written in English
4/5 of 600 = 2400 /5 = 480 Chinese books.

English 600
Chinese 480
