If a = 2 and b = 3, find the value of (i) a + b (ii) a^(2) + ab (iii) ab - a^(2) (iv) 2a - 3b (v) 5a^(2) - 2ab (vi) a^(3) - b^(3)

Simplify combining like terms: 3a-2b-ab-(a-b+ab)+3ab+b-a

Factorise each of the following : (i) 8a^(3)+b^(3)+12a^(2)b+6ab^(2) (ii) 8a^(3)-b^(3)-12a^(2)b+6ab^(2) (iii) 27-125a^(3)-135a+225a^(2) (iv) 64a^(3)-27b^(3)-144a^(2)b+108ab^(2) (v) 27p^(3)-(1)/(216)-(9)/(2)p^(2)+(1)/(4)p

Factorise each of the following : (i) 8a^3+b^3+12a^2b+6ab^2 (ii) 8a^3-b^3-12a^2b+6ab^2 (iii) 27-125a^3-135a+225a^2 (iv) 64a^3-27b^3-144a^2b+108ab^2 (v) 27p^3-1/(216)-9/2p^2+1/4p s

Simplify combining like terms: 3a - 2b - ab - (a - b + ab) + 3ab + b - a

a^3 - b^3 - 3a^2b+ 3ab^2, by, a^2 + b^2 - 2ab

a^(3)+3a^(2)b+3ab^(2)+b^(3) divided by a^(2)+2ab+b^(2) is

If a + b+ c= p and ab + bc + ca= q , find a^(2) +b^(2) + c^(2)

If a+b+c=p and ab+bc+ac=q, find a^(2)+b^(2)+c^(2) .
