3ab^3-3a^3b eching

$$3 a b ^ { 3 } - 3 a ^ { 3 } b$$

Omil

$$3ab\left(b-a\right)\left(a+b\right)$$

Yechim qadamlari

3 omili.

$$3\left(ab^{3}-a^{3}b\right)$$

Hisoblang: ab^{3}-a^{3}b. ab omili.

$$ab\left(b^{2}-a^{2}\right)$$

Hisoblang: b^{2}-a^{2}. Kvadratlarning farqini ushbu formula bilan hisoblash mumkin: p^{2}-q^{2}=\left(p-q\right)\left(p+q\right).

$$\left(b-a\right)\left(b+a\right)$$
