" Pactorise "-a^(7)-ab^(6)

factorise a^(7)-ab^(6)

Factorize: a^(7)+ab^(6)

Factorize each of the following expressions: a^(6)-b^(6)( ii) a^(6)+b^(6) (iii) a^(7)+ab^(6)

Factroise (i) 2a^7-128a (ii) a^7+ab^6 (iii) 32a^3+108b^3

If a+ b = 7 and ab= 6, find a^(2) - b^(2)

Find each of the products: (7ab)x(-5ab^(2)c)x(6abc^(2))

If a=(sqrt(7)-sqrt(6))/(sqrt(7)+sqrt(6)) and b=(sqrt(7)+sqrt(6))/(sqrt(7)-sqrt(6)), then find the value of a^(2)+b^(2)+ab

If a=(sqrt(7)-sqrt(6))/(sqrt(7)+sqrt(6)) and b=(sqrt(7)+sqrt(6))/(sqrt(7)-sqrt(6)), then find the value of a^(2)+b^(2)+ab

Factorise the following : 3a^(2)+7ab -6b^(2)

Find the sum of the expresson - 15 a ^(2) + 3 ab - 6b ^(2) a ^(2) - 5 ab + 11 b ^(2) , - 7a ^(2)- 18 ab - 13 b ^(2) and 26 a ^(2) - 16 ab - 7b ^(2).
