Completely WRONG Solution to an Equation (can you find the mistakes?)

In this video I show you the worst possible solution to an equation. It is full of mistakes. Can you find them? Leave a comment outlining the mistakes. Also, make sure to subscribe to the channel so you never make another math mistake again :)

That actually breaks my heart. There are so many mistakes. Here there are:

[@niklasnowak9010]

Please tell me you made this up yourself and theres actually noone who thinks thats the way it works.

😂😂😂😂

[@Anonymous_952]

I nearly had a stroke watching the wrong solution

Great sequel to the “10 most common mistakes video”

Solution

[@ChavoMysterio]

2x³-7x²-2x=2x

[@user-kc5dr5lo3j]

Errors:

[@Fire_Axus]

you cannot distribute powers over addition

[@mibsaamahmed]

1-the square roots were messed up, the 2 was also supposed to have the square root

[@hardcorecheese5998]

This gave me a headache.

Just when I thought it couldn’t get any worse, it did.

First mistake I found is dividing by x. This is assuming x = 0 is not a solution but since every term has an x in it x= 0 is a valid solution. The student has therefore lost a perfectly valid solution, which is ironic since in hindsight the student actually found x = 0 as the solution which should have rang alarm bells as we can't divide by zero.

[@Fire_Axus]

logarithms do not distribute over addition

[@beatdestroyer1682]

Ok so I haven’t done logarithms yet but I have found a few errors up to when the logs come in:

1. in line 3, you square rooted the term: 2(x^2), which you simplified to 2x. This should simplify to sqrt(2)*x.

[@aku7598]

Since x = 0 is one of the solutions by looking at equation,

[@aguy5321]

This polynomial equation should have 3 solutions

[@DeepakPal-wf1my]

There will be an identity of (a-b)^2= a^2+b^2-2ab
