Question on Algebraic Expressions and Identities

Hi OneDirection

What is the value of x2 - 2xy + y2 if x=0 and y=1 ?

just substitute those values of x and y in :)

\(x^2-2xy+y^2\quad where \;x=0\;\;and\;\;y=1\\ 0^2-2*0*1+1^2\\ =0-0+1\\ =1\)

Verse 1]
[Liam]
You're insecure,
Don't know what for,
You're turning heads when you walk through the door,
Don't need make-up,
To cover up,
Being the way that you are is enough,

[Bridge]
[Harry]
Everyone else in the room can see it,
Everyone else but you,

[Chorus]
[All]
Baby you light up my world like nobody else,
The way that you flip your hair gets me overwhelmed,
But when you smile at the ground it ain't hard to tell,
You don't know,
Oh, oh,
You don't know you're beautiful,
If only you saw what I can see,
You'd understand why I want you so desperately,
Right now I'm looking at you and I can't believe,
You don't know,
Oh, oh,
You don't know you're beautiful,
Oh, oh,
That's what makes you beautiful

[Verse 2]
[Zayn]
So c-come on.
You got it wrong.
To prove I'm right
I put it in a song.
I don't know why
You're being shy,
And turn away when I look into your eye-eye-eyes,

[Bridge]
[Harry]
Everyone else in the room can see it,
Everyone else but you,

[Chorus]
[All]
Baby you light up my world like nobody else,
The way that you flip your hair gets me overwhelmed,
But when you smile at the ground it ain't hard to tell,
You don't know,
Oh oh,
You don't know you're beautiful,
If only you saw what I can see,
You'll understand why I want you so desperately,
Right now I'm looking at you and I can't believe,
You don't know,
Oh oh,
You don't know you're beautiful,
Oh oh,

[Harry]
That's what makes you beautiful

Na na na na na na na na na na
Na na na na na na [x2]

[Harry]
Baby you light up my world like nobody else,
The way that you flip your hair gets me overwhelmed,
But when you smile at the ground it ain't hard to tell,

[All]
You don't know,
Oh oh,
You don't know you're beautiful,

[Chorus]
[All]
Baby you light up my world like nobody else,
The way that you flip your hair gets me overwhelmed,
But when you smile at the ground it ain't hard to tell,
You don't know,
Oh oh,
You don't know you're beautiful (Oh),
If only you saw what I can see,
You'll understand why I want you so desperately ([Harry:] desperately),
Right now I'm looking at you and I can't believe,
You don't know,
Oh oh,
You don't know you're beautiful,
Oh oh,
You don't know you're beautiful,
Oh oh,

[Harry]
That's what makes you beautiful
 

The answer is learn AS maths and then answer the question and if you can't, unlucky!

I love that song guest!!!!!!!!!!!!

I asked the answer, not the lyrics of 'What Makes You Beautiful' made by us.

Thanks Melody!
