Réitigh 128am^2-242an^2

$$128 a m ^ { 2 } - 242 a n ^ { 2 }$$

Fachtóirigh

$$2a\left(8m-11n\right)\left(8m+11n\right)$$

Céimeanna Réitigh

Fág 2 as an áireamh.

$$2\left(64am^{2}-121an^{2}\right)$$

Mar shampla 64am^{2}-121an^{2}. Fág a as an áireamh.

$$a\left(64m^{2}-121n^{2}\right)$$

Mar shampla 64m^{2}-121n^{2}. Athscríobh 64m^{2}-121n^{2} mar \left(8m\right)^{2}-\left(11n\right)^{2}. Is féidir an riail seo a úsáid chun difríocht na n-uimhreacha cearnacha a fhachtóiriú: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).

$$\left(8m-11n\right)\left(8m+11n\right)$$

Athscríobh an slonn iomlán fachtóirithe.

$$2a\left(8m-11n\right)\left(8m+11n\right)$$

Luacháil
