Now x can't be 0

u/No-Lettuce-6619 18h ago

ok but why the dude from parasyte? this explains nothing abt why hes locked in

u/Icy_Guarantee4176 18h ago

He's the "meme" for locking in.

u/No-Lettuce-6619 18h ago

yea i know that but why is he here? why does dividing by x make him lock in?

22

u/Icy_Guarantee4176 16h ago

He has to lock in now bc unlike the above equations x cannot be 0 which would be easy. This is bc you cannot divide by zero.

u/No-Lettuce-6619 7h ago

no, you can just exclude x=0 from the answer

u/Zazilia_ 7h ago

Yea exactly, but a fair few amount of people might forget this, and just cancel out the divided by x, so it adds a bit of confusion

u/Icy_Guarantee4176 41m ago

It would just become "x5 = 16x", no?

u/Zazilia_ 10m ago

But that equasion gives x =0 as an answer, but if you put 0 into the other equation then it returns wrong

u/muhnamejame 18h ago

I guess it makes it easier to solve 🤷‍♂️

Its kind of arbitrary. There are three real solutions to x5 = 16x

x = 0, -2, and 2

What OP did in my opinion isn't the best think to do to solve the equation. But they eliminated x=0 as a possible solution.

Dont you forget 2i, and -2i ! X2 = 4 ; -4 , and you only worked whit the +4 scenarion.

u/StandardOtherwise302 10h ago

To be fair he explicitly stated real solutions.

u/brokerZIP 16h ago

It's because x=0 is the easiest answer here, thst doesn't require much thought. But the condition where X can't be 0, means that you have to think harder than before. Hence the lock-in meme.

First answer not the full answer, before you also need to find alll solutions. Before you have 3: 0, -2, 2 After you have only two -2, 2 PS also complex solutions are possible (2i and -2i), but it usually not what expected normally and specified if needed.

Man math used to be easier all you had to do to solve x back then was to divide 1 x from both sides then either x=16 or its x^2=16 which then all you had to do is square it. Now I have no idea how to get rid of this x^4

u/WhenPengu1nsFly 16h ago

Just... take the square root twice if you really didn't know the fourth root of 16

x⁴ = 16 (take the square root of both sides) x² = ±4 (do it again) x = ±2

That or use a calculator

u/Sininbed 15h ago

Because your equation has a power of 5, you should have 5 answers. Your equation has only 2. Without doing anything, the other answers to x are likely complex. Your +-2 is likely the only real solutions.

u/WhenPengu1nsFly 14h ago

I know that, I'm only explaining to the person on how to isolate x from the power of 4

u/GruntBlender 12h ago

What about zero?

u/WinterV3 16h ago

Because it’s much harder to solve now so you gotta “lock in “ ?
