Céimeanna chun Cothromóidí Líneacha a Réiteach

Méadaigh an dá thaobh den chothromóid faoi \epsilon .

$$\epsilon \epsilon -x\epsilon =\left(I-x\right)f$$

Méadaigh \epsilon agus \epsilon chun \epsilon ^{2} a fháil.

$$\epsilon ^{2}-x\epsilon =\left(I-x\right)f$$

Úsáid an t-airí dáileach chun I-x a mhéadú faoi f.

$$\epsilon ^{2}-x\epsilon =If-xf$$

Athraigh na taobhanna ionas go mbeidh na téarmaí inathraitheacha ar fad ar an taobh clé.

$$If-xf=\epsilon ^{2}-x\epsilon$$

Cuir xf leis an dá thaobh.

$$If=\epsilon ^{2}-x\epsilon +xf$$

Tá an chothromóid i bhfoirm chaighdeánach.
