Question

3root3a cube – b cube - 5root 5c cube - 3 root 15abc factorize it fast ​

Answer 1

Answer:

(√3a-b-√5c) (3a^2+b^2+5c^2+√3ab-√5bc+√15ac)

Explanation:

(√3a)^3+(-b)^3+(-√5c)^3-3(√3a)(-b)(-√5c)

By using the following formula

a^3+b^3+c^3-3abc=(a+b+c) (a^2+b^2+c^2-ab-bc-ca)

=(√3a-b-√5c) (3a^2+b^2+5c^2+√3ab-√5bc+√15ac)
