Question

n2+ 601n - 162000=0​

Answer 1

Answer:

Step-by-step explanation:

n2-n=0  

Two solutions were found :

n = 1

n = 0

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "n2"   was replaced by   "n^2".  

Step by step solution :

Step  1  :

Step  2  :

Pulling out like terms :

2.1     Pull out like factors :

  n2 - n  =   n • (n - 1)  

Equation at the end of step  2  :

 n • (n - 1)  = 0  

Step  3  :

Theory - Roots of a product :

3.1    A product of several terms equals zero.  

When a product of two or more terms equals zero, then at least one of the terms must be zero.  

We shall now solve each term = 0 separately  

In other words, we are going to solve as many equations as there are terms in the product  

Any solution of term = 0 solves product = 0 as well.

Solving a Single Variable Equation :

3.2      Solve  :    n = 0  

 Solution is  n = 0

Solving a Single Variable Equation :

3.3      Solve  :    n-1 = 0  

Add  1  to both sides of the equation :  

                     n = 1

Two solutions were found :

n = 1

n = 0
