Question

x2-7x+=0. solve the equation

Answer 1

Answer:

x=7

x=0

Step-by-step explanation:

STEP1:

STEP2:Pulling out like terms

 2.1     Pull out like factors :

   x2 - 7x  =   x • (x - 7) 

Equation at the end of step2:

x • (x - 7) = 0

STEP3: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  :    x = 0 

  Solution is  x = 0 

Solving a Single Variable Equation:

 3.3      Solve  :    x-7 = 0 

 Add  7  to both sides of the equation : 

                      x = 7 

Two solutions were found :

 x = 7

 x = 0
