Question

Solve 5y(y-4)=0 please hurry!

Answer 1

Answer:

y = 4

y = 0

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 5y • (y - 4)  = 0  

Step  2  :

Theory - Roots of a product :

2.1    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 :

2.2      Solve  :    5y = 0  

Divide both sides of the equation by 5:

                    y = 0

Solving a Single Variable Equation :

2.3      Solve  :    y-4 = 0  

Add  4  to both sides of the equation :  

                     y = 4

Hope this helps
