The Difference of Two Squares - GCSE mathematics

[@mohammedhafiz8522]

This is by far the best explanation of D.O.T.S thanks

[@wehereforthebars5658]

Thanks actually writing a test tomorrow 😬

[@tkayah812]

I'm writing a huge test tomorrow, this really help😊

[@joshuaedemsokon1888]

X⁴-Y⁴
(x²)²-(y²)²
x(x+2)-y(y+2)
Pls from here which step should I take or should be allowed this way

[@aryasrafiq3428]

i think its (x-y)(x+2)(y+2)

[@talli-studios]

fr yes thanks

[@jmoney5097]

Very nice Video! :)

[@newkosan3399]

Thank you 😭

[@kerosene188]

Can you do a videos solving international math papers please? That was a great video btw

[@mathonify]

Which set?

[@kerosene188]

@@mathonify Pure mathematics 2 WMA12/01 or Statistics 1 WST01/01

[@mathonify]

I’ll check if I can get them and if so I’ll get them done

[@idrk1507]

What is the last one (7)? I did it but just in case I want to check

[@bagakilo]

is the last 1 (x^2)^2-(y^2)^2
so the answer is: (x^2+y^2)(x^2-y^2) ?

[@hillidingi6184]

can you do a video for questions about like 5xy - 10y squad

[@Aizosan]

I have a test tomorrow shit 🏃🏽‍♂️

[@augustineasoghogu2888]

Solve 20msquare + 10m

[@iviebuso3879]

x⁴-y⁴
(x²+y²) (x²-y²)
(x+y) (x-y)
I have no idea 😭😭

[@mathonify]

That’s exactly right

[@mohamedkhalid6553]

I think that you made a mistake in number 6

[@hasanaldhubaibi3590]

what is the mistake?

[@joshuaedemsokon1888]

Am I correct
My answer is (x+y)(x-y)
Soln
X⁴-Y⁴
(X)²-(y)²
(x+y)(x-y)

[@mathonify]

Step 2 should be (x^2)^2-(y^2)^2

[@joshuaedemsokon1888]

But the answer is correct?

[@mathonify]

No. Think about what the next step should be after step 2 following the rules in the video.

[@jasonnong3305]

@@mathonify If they both have a common factor of 2 squared, then can I re-arrange it so that (x^2)^2 - (y^2)^2 = (x^2 - y^2)^2 = ((x + y)(x - y))^2 ?

[@mathonify]

@@jasonnong3305 getting there. Your first expression is the correct next step. Use completing the square on (x^2)^2 - (y^2)^2. You have two squared terms subtracted.

I'm Arabic and I don't understand anything 🤣🤣

[@facts-ec4yi]

okay?
