3b^4+18b^3+27b^2 eching

$$3 b ^ { 4 } + 18 b ^ { 3 } + 27 b ^ { 2 }$$

Omil

$$3b^{2}\left(b+3\right)^{2}$$

Yechim qadamlari

3 omili.

$$3\left(b^{4}+6b^{3}+9b^{2}\right)$$

Hisoblang: b^{4}+6b^{3}+9b^{2}. b^{2} omili.

$$b^{2}\left(b^{2}+6b+9\right)$$

Hisoblang: b^{2}+6b+9. Kvadrat formuladan foydalaning, p^{2}+2pq+q^{2}=\left(p+q\right)^{2}, bu yerda p=b va q=3.

$$\left(b+3\right)^{2}$$

Toʻliq ajratilgan ifodani qaytadan yozing.

$$3b^{2}\left(b+3\right)^{2}$$

Baholash

$$3\left(b\left(b+3\right)\right)^{2}$$
