25x^(2)+4y^(2)+9z^(2)-20xy-12yz+30xz

Factorise the following expression: ( i) 4x^(2) +9y^(2) +25z^(2) +12xy +30yz + 20zx (ii) 25x^(2) +4y^(2) +9z^(2) -20 xy +12yz - 30zx

Factories the following : 25x^(2) + 4y^(2) + 9z^(2) - 20 xy + 12yz + 30 xz

Facorise the following (i) 9x^(2)+4y^(2)+16z^(2)+12xy-16yz-24xz (ii) 25x^(2)+16y^(2)+4z^(2)-40xy+16yz-20xz (iii) 16x^(2)+4y^(2)+9z^(2)-16xy-12yz+24xz

Facorise the following (i) 9x^(2)+4y^(2)+16z^(2)+12xy-16yz-24xz (ii) 25x^(2)+16y^(2)+4z^(2)-40xy+16yz-20xz (iii) 16x^(2)+4y^(2)+9z^(2)-16xy-12yz+24xz

Factorise the following (i) 9x^(2)+4y^(2)+16z^(2)+12xy-16yz-24xz (ii) 25x^(2)+16y^(2)+4z^(2)-40xy+16yz-20xz (iii) 16x^(2)+4y^(2)+9z^(2)-16xy-12yz+24xz

Find the following produts: (i) (x+y+2z)(x^(2)+y^(2)+4z^(2)-xy-2yz-2xz)(2x-y+2z)(4x^(2)+y^(2)+9z^(2)+2xy+3yz-6xz)

Simplify : (x- 2y + 3z ) ( x^(2) + 4y^(2) + 9z^(2) + 2xy + 6yz - 3xz)

Factorise : - 4x^(2) +9y^(2)+16z^(2)+12xy-24yz-16xz
