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 😬

[@idrk1507]

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

[@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

[@tkayah812]

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

[@bagakilo]

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

[@jmoney5097]

Very nice Video! :)

[@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)

[@hillidingi6184]

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

[@newkosan3399]

Thank you 😭

[@talli-studios]

fr yes thanks

[@Aizosan]

I have a test tomorrow shit 🏃🏽‍♂️

[@mohamedkhalid6553]

I think that you made a mistake in number 6

[@hasanaldhubaibi3590]

what is the mistake?

[@iviebuso3879]

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

[@mathonify]

That’s exactly right

[@augustineasoghogu2888]

Solve 20msquare + 10m

[@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.

[@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.

[@Vivian-glory]

@@mathonify I really love ur video and the teaching is great.
Pls I have a worry... I'm not a math person BTW
From the last problem u solved that had 50.... And u applied 25^2... But 25^2 isn't 50, its 625.
From my logical view 25 wasn't the figure to be used....
Can u pls explain for better understanding?
Thanks. Thats the only place where I got a hard time understanding.
