`(i) (x^3-x)`
`(ii) 18a^2x^2-32)`
`(iii) (2a^5-32a)`.

Factroize (i) x^2-1-2a-a^2 (ii) 1+2ab-(a^2+b^2)

Factorise: (i) x^(3)-2x^(2)-x+2 (ii) x^(3)-3x^(2)-9x-5 (iii) x^(3)+13x^(2)+32x+20 (iv)

Factorise: (i) x^3-2x^2-x+2 (ii) x^3-3x^2-9x-5 (iii) x^3+13 x^2+32 x+20 (iv) 2y^3+y^2-2y-1

Factories : (i) x^3-2x^2-x+2 (ii) x^3-3x^2-9x-5 (iii) x^3+13x^2+32x+20 (iv) 2y^3+y^2-2y-1

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

Expand each of the following (i) (2x+5y)^(2) (ii) (x-3y)^(2) (iii) (x+5)(x-3)

Factorise: 2x-32x^3

(i) 2x^(2)-17x+21 =0 (ii) 5y^(2)-32 + 35 = 0

Factorise (i) x ^(2) - 2x ^(2) - x +2 (ii) x ^(3) - 3x ^(2) - 9x -5 (iii) x ^(3) + 13 x ^(2) + 32 x + 20 (iv) y ^(3) + y ^(2) -y -1
