" 12."x^(2)-y^(2)-4xz+4z^(2)

Factorize: x^(2)-y^(2)-4xz+4z^(2)

Factorize each of the following algebraic expressions: a^(2)+2ab+b^(2)-c^(2)(2)49-x^(2)-y^(2)+2xya^(2)+4b^(2)-4ab-4c^(2)(4)x^(2)-y^(2)-4xz+4z^(2)

Factorise : 3x^(2)+4xy+y^(2)-2xz-z^(2)

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

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

If xy+yz+xz=1, then prove that (x)/(1-x^(2))+(y)/(1-y^(2))+(z)/(1-z^(2))=(4xyz)/((1-x^(2))(1-y^(2))(1-z^(2)))
