`9-a^2+2ab-b^2`

Factorize each of the following algebraic expressions: 4x^(2)+12xy+9y^(2)(2)9a^(2)-24ab+16b^(2)p^(2)-6pqr+9r^(2)(4)36a^(2)+36a+9a^(2)+2ab+b^(2)-16(6)9z^(2)-x^(2)+4xy-4y^(2)

Prove: |[a^2, 2ab,b^2],[b^2,a^2, 2ab],[2ab,b^2,a^2]|=(a^3+b^3)^2

If 9a^(2)-6ab+b^(2)=0 then find a:b

Factorles: 12a ^(2) b- 9ab^(2) + 6ab

factorize : a^2+2ab +b^2-9c^2

Simplify using following identiy: (a +- b) (a^(2) ab + b^(2)) = a^(3) +- b^(3) ((a)/(3)-3b) ((a^(2))/(9) + ab + 9b^(2))

What is the HCF of a^2b^4+2a^2b^2 and (ab)^7 - 4a^2b^9

Verify the identity (a + b)^(2) -= a^(2) + 2ab + b^(2) geometrically by taking a = 5 units, b = 9 units
