Answer 1

Step-by-step explanation:

answer=30a^7b^4

hope it will help you

Answer 2

Final result :

 a • (a2 - 3ab + 5b2)

Step by step solution :

Step  1  :

Equation at the end of step  1  :

 ((a3)-((3•(a2))•b))+5ab2

Step  2  :

Equation at the end of step  2  :

 ((a3) -  (3a2 • b)) +  5ab2

Step  3  :

Step  4  :

Pulling out like terms :

4.1     Pull out like factors :

  a3 - 3a2b + 5ab2  =   a • (a2 - 3ab + 5b2)  

Trying to factor a multi variable polynomial :

4.2    Factoring    a2 - 3ab + 5b2  

Try to factor this multi-variable trinomial using trial and error  

Factorization fails

Final result :

 a • (a2 - 3ab + 5b2)
