\left(2x\right)^{2}-y^{2}+\left(x+y\right)^{2}-2\left(x^{2}-xy\right)

Mar shampla \left(2x+y\right)\left(2x-y\right). Is féidir iolrúchán a athrú ó bhonn go dtí difríocht na gcearnóg ag úsáid na rialach seo: \left(a-b\right)\left(a+b\right)=a^{2}-b^{2}.

2^{2}x^{2}-y^{2}+\left(x+y\right)^{2}-2\left(x^{2}-xy\right)

Fairsingigh \left(2x\right)^{2}

4x^{2}-y^{2}+\left(x+y\right)^{2}-2\left(x^{2}-xy\right)

Ríomh cumhacht 2 de 2 agus faigh 4.

4x^{2}-y^{2}+x^{2}+2xy+y^{2}-2\left(x^{2}-xy\right)

Úsáid an teoirim dhéthéarmach \left(a+b\right)^{2}=a^{2}+2ab+b^{2} chun \left(x+y\right)^{2} a leathnú.

5x^{2}-y^{2}+2xy+y^{2}-2\left(x^{2}-xy\right)

Comhcheangail 4x^{2} agus x^{2} chun 5x^{2} a fháil.

5x^{2}+2xy-2\left(x^{2}-xy\right)

Comhcheangail -y^{2} agus y^{2} chun 0 a fháil.

5x^{2}+2xy-2x^{2}+2xy

Úsáid an t-airí dáileach chun -2 a mhéadú faoi x^{2}-xy.

3x^{2}+2xy+2xy

Comhcheangail 5x^{2} agus -2x^{2} chun 3x^{2} a fháil.

3x^{2}+4xy

Comhcheangail 2xy agus 2xy chun 4xy a fháil.
