Factorise the following using appropriate identities.
(i) `16x ^(2) + 24xy + 9y ^(2)`
(ii) `4y ^(2) - 4y +1`
(iii) `4x ^(2) - (y ^(2))/( 25)`
(iv) `18a ^(2) - 50`
(v) ` x ^(2) + 5x + 6`
(vi) `3p ^(2) - 24 p + 36`

Answer

(i) ` (4x + 3y) ^(2) `
(ii) `(2y -1) ^(2)`
(iii) `(2x + (y)/(5)) (2x - (y)/(5))`
(iv) ` 2 (3a +5) (3a -5)`
(v) `(x+3) (x+2)`
(vii) `3(P -6) (P-2)`
