27x^(3)+108x^(2)y+144xy^(2)+64y^(3)

Check whether the following are perfect squares or not : (a) 64x^(2) + 81y^(2) - 144 xy (b) 4x^(2) + 8y^(2) + 16 xy

Factorise : 27x^(3) - 64y^(3) - 108 x^(2)y + 144 xy^(2)

Add : x^(3) - x^(2)y + 5xy^(2) + y^(3) , -x^(3) - 9xy^(2) + y^(3), 3x^(2)y + 9xy^(2)

27x^(3)y^(3)-45x^(4)y^(2)

Factorise the following expression: (i) 8x^(3) +125y^(3) (ii) 27x^(3) -8y^(3) (iii) a^(6) -64

The following are the steps involved in factorizing 64 x^(6) -y^(6) . Arrange them in sequential order (A) {(2x)^(3) + y^(3)} {(2x)^(3) - y^(3)} (B) (8x^(3))^(2) - (y^(3))^(2) (C) (8x^(3) + y^(3)) (8x^(3) -y^(3)) (D) (2x + y) (4x^(2) -2xy + y^(2)) (2x - y) (4x^(2) + 2xy + y^(2))

Factorize each of the following expressions: 16x^(2)-25y^(2) (2) 27x^(2)-12y^(2)144a^(2)-289b^(2) (4) 12m^(2)-27125x^(2)-45y^(2)(6)144a^(2)-169b^(2)

Factorise : 8x^(3) + 27y^(3) + 36x^(2)y + 54xy^(2)
