Answer:
  
Step-by-step explanation:
 Remember:
 ![(\sqrt[n]{a})^n=a\\\\(a+b)=a^2+2ab+b^2](https://tex.z-dn.net/?f=%28%5Csqrt%5Bn%5D%7Ba%7D%29%5En%3Da%5C%5C%5C%5C%28a%2Bb%29%3Da%5E2%2B2ab%2Bb%5E2)
 
 Given the equation  , you need to solve for the variable "x" to find its value.
, you need to solve for the variable "x" to find its value.
 You need to square both sides of the equation:
 
 
 Simplifying, you get:
 
 Factor the quadratic equation. Find two numbers whose sum be 7 and whose product be -8. These are: -1 and 8:
 
 Then:
 
 Let's check if the first solution is correct:
 
  (It checks)
 (It checks)
 Let's check if the second solution is correct:
 
  (It does not checks)
 (It does not checks)
 Therefore, the solution is:
 
 
        
             
        
        
        
Answer:  total books = 180
Step-by-step explanation:
Given: Poetry section of the library has 6 bookcases.
Number of shelves in each bookcase = 3
Total shelves =  (Number of shelves in each bookcase) x (Number of bookcases in each poetry section)
= 3 x 6
= 18
Number of books in each shelf = 10
Total books = (number of shelves) x 10
= 18 x 10
= 180
hence, total books in the poetry section= 180
