dude:

Do you have an idea or are just completely lost?

UltraInstinct:

lost as a blind person in the woods

dude:

You want to factor out \(18x^2-32\)

UltraInstinct:

okayy... uhm i can do that probably ig

dude:

Do you wan me to show you how to factor it?

UltraInstinct:

yes pls lol

dude:

The question shows that 2 has been factored out so just factor out the 2 from \(18x^2-32\) =\(2(9x^2-16)\) Once you have this, just factor out \(9x^2-16\) both have multiples, 9 has 3 and 16 has 4, because the 16 is negative you need a (x+ number) and (x - number) So \(2(3x+4)(3x-4)\)

UltraInstinct:

uhhh wth how

UltraInstinct:

ok wait i get it

UltraInstinct:

so the missing thing is 4, and i would have never got that, and THANK YOU

dude:

Yes, and ofcs

dude:

You could've also reverse solved this

jhonyy9:

@dude can i derrange ?

jhonyy9:

what formule need using ? probably may help

jhonyy9:

different of squares

jhonyy9:

pardon for my interfer

dude:

Neh its okay, thanks for reminding me xD

UltraInstinct:

:|

jhonyy9:

anytime - np

UltraInstinct:

lol whut

dude:

\(9x^2-16\) is a difference of squares, basically both have a multiple that (squared) would equal the number \(3^2=9\) and \(4^2=16\) Because 16 is being subtracted its a difference (-) of squares

UltraInstinct:

oh ok, gotcha

UltraInstinct:

thx again

dude:
