Réitigh 125p^2r-180b^2r

$$125 p ^ { 2 } r - 180 b ^ { 2 } r$$

Fachtóirigh

$$5r\left(5p-6b\right)\left(5p+6b\right)$$

Céimeanna Réitigh

Fág 5 as an áireamh.

$$5\left(25p^{2}r-36b^{2}r\right)$$

Mar shampla 25p^{2}r-36b^{2}r. Fág r as an áireamh.

$$r\left(25p^{2}-36b^{2}\right)$$

Mar shampla 25p^{2}-36b^{2}. Athscríobh 25p^{2}-36b^{2} mar \left(5p\right)^{2}-\left(6b\right)^{2}. Is féidir an riail seo a úsáid chun difríocht na n-uimhreacha cearnacha a fhachtóiriú: m^{2}-n^{2}=\left(m-n\right)\left(m+n\right).

$$\left(5p-6b\right)\left(5p+6b\right)$$

Athscríobh an slonn iomlán fachtóirithe.

$$5r\left(5p-6b\right)\left(5p+6b\right)$$
