Divide :
`18a^(3)b^(2) - 27 a^(2)b^(3) +9ab^(2) by 3ab`

Factorise : a^(3) - 27b^(3) + 2a^(2)b - 6ab^(2)

Divide : 4a^(2) + 12ab + 9b^(2) - 25c^(2) by 2a + 3b + 5c

Add : 3ab^(2) , - 5ab^(2)

Factorise : a^(3) + 3a^(2)b + 3ab^(2) + 2b^(3) .

Factorise: a^(3) + ab (1-2a) - 2b^(2)

Multiply : 3a^(2)b - 5ab" by " 3ab

Multiply 8a^(2)b - 3ab + 5b^(2) by 6ab.

Factorise : a^(2)b^(2) + 8ab - 9

Find the angle between the lines , (a^(2) - ab) y = (ab+b^(2))x+b^(3) , and (ab+b^(2)) y = (ab-a^2)x+a^(3) where a lt b lt 0

Multiply : 2a^(3) - 3a^(2)b and -(1)/(2)ab^(2)
