quadratics

[subtle tundra]

can i find the area to find x then use that to find the perimeter?

1. Wait patiently for a helper to come along.
2. Once someone helps you, say thank you and close the thread with:

+close

3. Feel free to nominate the person for helper of the week in #helper-nominations
4. Do not ping the mods, unless someone is breaking the rules.
5. If you're happy with the help you got here, and the server overall, you can contribute financially as well:

is the area given?

because you can just add up the side lengths for the perimeter

[subtle tundra]

nope

[subtle tundra]

i did that

but the answer doesnt have x in it

so im like it cant be that easy yk?

like it shouldnt be that straightforward

[nimble crow]

is that everything the question gives you

[subtle tundra]

mhm

[nimble crow]

oh

use pygor theorem

[subtle tundra]

but all the sides are known

[nimble crow]

you can solve x

I think

[subtle tundra]

wdym

cuz this entire exercise

is abt quadratic formulas

[nimble crow]

yea

how would you use the Pythagorean theorem here?

[subtle tundra]

o

[nimble crow]

you will get a quadratic to solve

[subtle tundra]

(x+4)^2=x^2+(x+3)^2

@nimble crow

[nimble crow]

now solve!!

[subtle tundra]

alrr

ill ping u

[nimble crow]

it’s a quadratic :D

[subtle tundra]

if i get

anymore

problems

[subtle tundra]

tysm

yw

[subtle tundra]

uhmm

would it be

set out

like

[subtle tundra]

this?

would i expand the brackets

[nimble crow]

yea

it forms a quadratic

[subtle tundra]

do i move the x^2+16

to the right

to make an NFL

[nimble crow]

you want it as

$ax^{2} +bx+c$

[unkempt atlas]

!𒐪 ɹɐupoɯ⇂ㄥ8𝟝 𒐪!

[hard turret]

[subtle tundra]

hm

[subtle tundra]

[subtle tundra]

cuz idk where the bx went

cuz rn i got

[nimble crow]

uhh

[subtle tundra]

$x^{2}+16=x^{2}+x^{2}+9$

[unkempt atlas]

vincent.

[subtle tundra]

mb

its this one

i expanded the brackets

[nimble crow]

$(x+a)^{2} = x^{2} +2ax+a^{2}$

[unkempt atlas]

!𒐪 ɹɐupoɯ⇂ㄥ8𝟝 𒐪!

[nimble crow]

$not x^{2} +a^{2}$

[unkempt atlas]

!𒐪 ɹɐupoɯ⇂ㄥ8𝟝 𒐪!

[subtle tundra]

hm?

[nimble crow]

expand (x+4)^2 pls?

[subtle tundra]

x^2 +16

[sleek thicket]

2x²+6x+9=x²+8x+16

[subtle tundra]

o

shit

i c

now

omg

[nimble crow]

yea that’s not how you expand

[subtle tundra]

i was dumb

[nimble crow]

lmao

[subtle tundra]

ye mb

i did it wrong

[sleek thicket]

x²-2x-7=0

[subtle tundra]

💀

x^2+8x+16

@nimble crow

sorry

i was squaring the things inside

[nimble crow]

yea

now simplify

[subtle tundra]

alr

i think

i got it now

[unkempt atlas]

[sleek thicket]

can't have negative length, so the positive root

[nimble crow]

nooo stop solving the whole question

bad

[nimble crow]

what’s the latex for this

the question mark react is not working

[sleek thicket]

10+6√2 the end

[sleek thicket]

why

[nimble crow]

curious

[sleek thicket]

it's simple

frac pm sqrt

[nimble crow]

oh pm

[subtle tundra]

i did it

tysm

[subtle tundra]

howd u do that +/- sign with the bot?

@nimble crowsince i got 2 solutions

which one do i use

to find the perimeter

[nimble crow]

the positive one

[subtle tundra]

or will there be 2 answers

alr

[nimble crow]

negative ones cannot be the answer

since a side can’t be negative

[subtle tundra]

imma use the calc

[magic pecan]

if there are 2 answers that are both geometrically valid, you can put both

[subtle tundra]

since i got the final answer

[sleek thicket]

I literally explained!!!!!!!

[nimble crow]

does it want it in

$a+\sqrt(b)$

[unkempt atlas]

!𒐪 ɹɐupoɯ⇂ㄥ8𝟝 𒐪!

[sleek thicket]

yes

[nimble crow]

fail

[sleek thicket]

it wants exact form

[nimble crow]

oh yea

so @subtle tundra Don’t use a calculator

[sleek thicket]

a calculator will give you it in exact form

[subtle tundra]

mb i was mainly listening to @nimble crow sorry 😭

[sleek thicket]

provided you don't use approximate values in the middle

[nimble crow]

true

[subtle tundra]

mhm

using cas

[sleek thicket]

nah

doesn't need cas

[subtle tundra]

uh the answer was this

was i not supposed to simplify 2 +/- 4surd2 /2

[subtle tundra]

cuz i had this except that surd 32 was simplified

[magic pecan]

well its because you need to find the perimeter

[sleek thicket]

read what I said after that

your perimeter in terms of X is 3x+7

you have your x, you substitute and simplify

[subtle tundra]

whered the 10 come from

[sleek thicket]

simplifying

[subtle tundra]

ah ic ty
