(i) `x(x+1)(x+3)(x+4)=180` (ii) `(2x+3)(2x+5)(x-1) (x-2)=30`
(iii) `(x-5) (x-7)(x+4)(x+6)=504` (iv) `x(2x+1)(x-2) (2x-3)=63`
(v) `(x^(2)-3x-10)(x^(2)-5x-6)=144` (vi) `(x+2)(3x+4) (3x+7)(x+3)=2400`

Answer

(i) `-6, 2, -2 pm isqrt(11)` (ii) `0, -1/2, (-1 pm sqrt(105))/4` (iii) `-7, -2, 3, 8` (iv) `-3/2, 3, (3 pm isqrt(47))/4` (v) `-3,2,2,7`
(vi) `(-13 pm sqrt(601))/6, (-13 pm isqrt(575))/6`
