anonymous · Answer

Is it suppose to be -1 ?

tkhunny · Answer

No.  5 and $\sqrt{5}$ are not the same thing.

Hello, Ello,
May I suggest that you simplify the 2nd term of your result?

anonymous · Answer

It says to apply distributive property :o

tkhunny · Answer

Personally, I would never, ever write $\sqrt{5}\cdot\sqrt{5} = \sqrt{25}$ unless I was trying to make some point that doesn't come to mind.  $\sqrt{5}\cdot\sqrt{5} = 5$.

Just my opinion.

anonymous · Answer

This is what they put,

√5(4−√5)

(√5)(4)−(√5)(√5)

4√5−(√5•5)

4√5−5

−5+4√5

anonymous · Answer

I did it first on paper to see if i could do it on my own D:

tkhunny · Answer

Well, there you go.  Don't you dare write that "-1" and blue oval, again!

anonymous · Answer

O_O what?!

anonymous · Answer

So I'm suppose to just keep it -5 + 4sqr5 ?

tkhunny · Answer

What else were you planning to do with it?  There are no "like"  terms to process.

anonymous · Answer

Ohh i forgot that they're suppose to be like terms U_U -sigh-

Sanku :P
