so i need to get the resolution for a second grade disequation and i'm questioning myself if i can transform 1-x in x+1

#

anyone knows?

carmine rose Nov 3, 2023, 4:42 PM

#

ummm no

#

What is the question? You may share it

toxic minnow Nov 3, 2023, 4:45 PM

#

1-x is equal to x+1?

toxic minnow Nov 3, 2023, 4:46 PM

#

carmine rose What is the question? You may share it

if u want i can share how i did the disequation

toxic minnow 1-x is equal to x+1?

$1-x$ is not equal to $x-1$

carmine rose Nov 3, 2023, 4:55 PM

#

Take x = 3 for example

#

$1-3 \neq 3-1$

small starBOT Nov 3, 2023, 4:55 PM

Miguel

toxic minnow Nov 3, 2023, 4:59 PM

#

ok

#

about the disequation?

carmine rose Nov 3, 2023, 5:12 PM

#

toxic minnow

So this is the question right?

toxic minnow Nov 3, 2023, 5:15 PM

#

yes

toxic minnow Nov 3, 2023, 5:15 PM

#

toxic minnow

i need help with this

carmine rose Nov 3, 2023, 5:17 PM

#

hmmmm

#

Do you know the cubic formula?

toxic minnow Nov 3, 2023, 5:17 PM

#

no

carmine rose Nov 3, 2023, 5:17 PM

#

okk wait a sec

#

Ig I solved it but

#

It involves like finding the roots of a cubic polynomial

#

Please lemme reattempt

toxic minnow Nov 3, 2023, 5:18 PM

#

ok

carmine rose Nov 3, 2023, 5:22 PM

#

From where did you get this question?

#

Is it your hw?

toxic minnow Nov 3, 2023, 5:24 PM

#

yes

carmine rose Nov 3, 2023, 5:25 PM

#

hmmm if this is your hw then I'm wrong

#

btw here's what I did

#

distribute the (x-1)

#

so we get x - 1 - 3 < $\frac{6 - x^{2}}{1-x}$

toxic minnow Nov 3, 2023, 5:26 PM

#

ok

small starBOT Nov 3, 2023, 5:26 PM

#

AstroVortex

toxic minnow Nov 3, 2023, 5:26 PM

#

ok it's correct

carmine rose Nov 3, 2023, 5:26 PM

#

So we have $x-4<\frac{6-x^{2}}{1-x}$

small starBOT Nov 3, 2023, 5:27 PM

#

AstroVortex

carmine rose Nov 3, 2023, 5:27 PM

#

Now multiply both sides by (1 - x)^2

#

we have (x-4)(1-x)<6 - x^2

#

Now ig you can proceed

#

multiply (x-4)(x-1) to get a quadratic term and transpose 6-x^2 to the other side

#

You will kinda get a quadratic equation

#

Find its roots

#

but its not done yet

#

after finding the roots

#

lets say a and b

carmine rose Nov 3, 2023, 5:30 PM

#

carmine rose Now multiply both sides by (1 - x)^2

NO!!

#

NO

#

NO

#

NO

#

NO

#

????

#

multiply both sides by (1-x)^2

#

!!!

#

1-x is negative for x>1, that would flip the inequality

#

you have to account for both cases, when 1-x is positive and negative, or you can just multiply both sides by (1-x)^2 to guarantee it is positive

#

Oh so we have to solve it for both the cases

#

yes but dont do 2 cases, thats just extra work

#

its like having to do it twice

#

what is the original inequality?

#

If we multily by (1-x^2) won't we get a cubic??

#

you multiply by (1-x)^2 not (1-x^2)

carmine rose Nov 3, 2023, 5:33 PM

#

toxic minnow

This is the original inequality

carmine rose Nov 3, 2023, 5:33 PM

#

carmine rose you multiply by (1-x)^2 not (1-x^2)

oh yeah sry

toxic minnow Nov 3, 2023, 5:34 PM

#

thx can u help me with another one astro?

carmine rose Nov 3, 2023, 5:34 PM

#

Another one*? Did I help you previously?

toxic minnow Nov 3, 2023, 5:35 PM

#

yes

carmine rose Nov 3, 2023, 5:35 PM

#

when?? I don't remember lol

toxic minnow Nov 3, 2023, 5:35 PM

#

@toxic minnow

#

here is the solution

toxic minnow Nov 3, 2023, 5:39 PM

#

thx

#

im in 11th grande and i never knew infinite

carmine rose Nov 3, 2023, 5:39 PM

#

typically to solve inequalities, what you want to do is eliminate all of the fractions, remember to multiply by (f(x))^2 if it can be negative to both sides!! and then move it all to one side, and factorise, then simplify, and solve the quadratic/cubic to get the set of values

carmine rose Nov 3, 2023, 5:40 PM

#

toxic minnow im in 11th grande and i never knew infinite

ah my bad, i wrote it in interval notation

#

ill write it in a way you understand

toxic minnow Nov 3, 2023, 5:40 PM

#

thx

carmine rose Nov 3, 2023, 5:40 PM

at that is the cause why the quad didn't work
