What?

polar cedar
#

I know that this is true in a right angled triangle abc with c as the hypotenuse but I don’t know how to simplify this to a^2+b^2=c^2

#

a+b times by half of a+b

#

Yes

#

No

#

I think it can be simplified as (a^2+b^2+c^2)/2

polar cedar
#

Ok

#

Idk

median kayak
#

a^2+2ab+b^2

#

It's really easy

polar cedar
#

(a+b)^

#

Is multiplying fractions like 1/2*5/2=5/4

polar cedar
#

Oh Yh

#

So u times both sides by 2

muted oracle
#

Yes

polar cedar
#

Thanks

muted oracle
#

multiply

#

you do know (a+b)²

polar cedar
#

Yes

muted oracle
#

I hope you get it now

polar cedar
#

2ab+c^

muted oracle
#

yes keep going

polar cedar
#

How do u take brackets from (a+b)^

#

Is it a^+b^+2ab

#

Ohhh

#

Then u take 2ab and u get Pythagoras thing

#

Thanks
