what do you think?
i got noooo idea
gimme a sec
What you could always do with these are just plug in the values of x in to the equation a check with these one.
no its not
i just used a calculator
It has to be a single number with this
yes it is c actually
Take 45 to the right hand side, divide by 5 and get the square root of it.
uggggh im torn
Try to solve it without the use of calculators.
dang it so close i need 1 more medal
there you go
this is the working they showed me 5x^2 - 45 = 0 1. divide by 5 5(x^2 - 9) = 0 2. It's easy to factor the x^ - 9 polynomial! x^2- 9 = (x+3)(x-3) you can check this with FOIL if you want, but I promise it's right! So, the answer is: 5(x+3)(x-3)=0 x = 3, -3
but after you take the square root of both sides, doesn't that give you plus/minus root(9)?
Yeap. So now you got the answer. :D
i have a title now
lemme look at the post to see who gets the medal
i dont see the title
refresh your page
imma just give to my lil bro
I see it now
ummm...... I didnt help I'm 2 grades under u give it to someonelse
wait what grade are you in?
I meant i'm 3 grades under him
same here except i can get 100% on algebra 2 work
Then @Mumustar78612 should teach his little bro. ;D
@OregonDuck which grade are you in?
actually i'm pretty smart too
my mom sometimes thinks I'm better than him
Lot to learn. :0
I said SOMETIMES not all the time
my dad thinks i am smarter than my 10th grade sister
good for you
@Mahmood786123 I meant since you are in 6th grade there is a lot to learn. I am in my final year in school. :)
