`(a^3-b^3)/(a^2+b^2+ab)=`

If a+b=1 , then a^(4)+b^(4)-a^(3)-b^(3)-2a^(2)b^(2)+ab is equal to :

Factorise of the following. : 8a^3+b^3+12a^2b^2 + 6ab^2 .

Factorise of the following : 8a^3-b^3-12a^2b + 6ab^2 .

prove that , |{:(2ab,a^2,b^2),(a^2,b^2,2ab),(b^2,2ab,a^2):}|=-(a^3+b^3)^2

If a^2+b^2=135 and ab =7, (a>0, b>0) then what is the value of (a^3+b^3) ? यदि a^2+b^2=135 और ab = 7, (a>0, b>0) है तो (a^3+b^3) का मान है:

If (a^2 + b^2)^3 = (a^3 + b^3)^2 and ab != 0 then (a/b + b/a)^6 is equal to :

Factorise each of the following: 8a^3- b^3-12a^2b + 6ab^2
