गुणनखण्ड कीजिए :
(i) `4x^(2)-(1)/(9)`
(ii) `9x^(2)-(y+z)^(2)`
(iii) `(x+y)^(2)-9z^(2)`
(iv) `x^(2)-(y^(2))/(100)`
(v) `16x^(2)-25y^(2)`
(vi) `18x^(2)a^(2)-32`

Answer

(i) `(2x+(1)/(3))(2x-(1)/(3))`
(ii) `(3x+y+z)(3x-y-z)`
(iii) `(x+y+3z)(x+y-3z)`
(iv) `(x-(y)/(10))(x+(y)/(10))`
(v) `(4x-5y)(4x+5y)`
(vi) `2(3xa+4)(3xa-4)`
