Factorise the following : (i) `2x^(2)+9x+9` (ii) `2x^(2)+9x-5`

Answer

`(i) (2x+3)(x+3) " " (ii) (x+5)(2x-1) " "(iii) (3x-5)(2x+3)`
`(iv) 3x(x-6)(3x+8) " " (v) (1+x)(2x-1) " " (vi) (4-5x)(2x+3)`
`(vii) (7a+7b-ab)(a+b+7ab) " " (viii) sqrt(2)(x-sqrt(2))(7x+2sqrt(2)) " " (ix) (sqrt(2)x+1)(x+sqrt(2))`
`(x) (x+sqrt(17)y)(x-sqrt(17)y)(x^(2)+3y^(2)) " " (xi) (2x+3y)(13x-2y) " " (xii) (x+sqrt(2)y)(x+3sqrt(2)y)`
`(xii) (x+y+4)(x-6y+4) " " (xiv) (x+1)(x-1)(3x+1)(3x-5) " "(xv) (9x-4y)(2x+5y)`
