Zero Product Property | What is Zero Product Property and how to use it 

In this blog, I am going to discuss with you what is Zero product property, zero product property worksheet and how to use it.

 What Is Zero Product Property:

This property states that:

The product of two non zero elements is always a non zero number

Zero Product Property Worksheet:

The pic below has three examples of what is zero product property and I will explain them one by one.


Zero Product Property | What is Zero Product Property and how to use it


Example 1:


Dot means time or multiply and 0 of course is the result of multiplying these two quantities together,
so usually you'll see this written in your textbook as a times b equals 0  
and what it means is that either a is 0 because 0 times anything is 0 or B is 0 because 0 times anything is 0 or they're both 0 

Example 2:

Ok, if we know that this quantity is 0 or this quantity is 0 or they're both what we're going to do is we're just going to take each group 
because you can see these groups are multiplied together that's the product and we're going to set each of them equal to 0 so X plus 2 equals 0 or X minus 3 equals 0 now 

if we add 3 to both sides we're just solving these little mini equations here x equals 3 or if we subtract 2 from both sides we get x equals negative 2 so these are the two solutions to this equation 

now they don't always give it to you like this in the factored form they'll give it to maybe like as a polynomial or triangle me like this and what we want to do is we want to factor it first  

so it's a product of two factors and because it's equal to 0 we can use the zero product property to solve by setting each group to 0 so what we're gonna do here is we're gonna factor this first 

and you can see okay what multiplies to negative 12 that's negative 4 and positive 3 and let's just double-check negative 4x and positive 3x that's negative 1x right and action times X is x squared so we know we haven't factored correctly all we have to do now is set each group equal to 0 so you have X minus 4 equals 0 or X plus 3 equals 0 so you can see if we add 4 to both sides we get x equals 4 or if we subtract 3 from both sides you get x equals negative 3  

so again the zero product property is very easy it sounds a little bit mysterious but all you're doing is you're factoring or if it's already factored by setting each group equal to 0 you can then solve your equation so I hope this helped you understand how to work with it better subscribe to the channel check out more math videos on Mario's math tutor and YouTube channel and I look forward to helping in the future videos I'll talk to you soon
