this answer.. 3x(x+4)(x-5)
hahaha.........u are genius.:p
=> 4%2836x%5E2+%2B+1+-12x%29+-5+=223
=> 144x%5E2+-48x+%2B+4+-5+-223+=+0
=> 144x%5E2+-48x+-+224+=0
=> 9x%5E2+-+3x+-+14+=0
=> x=+%283%2Bsqrt%283%5E2-4%2A9%2A%28-14%29%29%29%2F%282%2A9%29 or x=+%283-sqrt%283%5E2-4%2A9%2A%28-14%29%29%29%2F%282%2A9%29
=> x=%281%2Bsqrt%2857%29%29%2F6 and x=%281-sqrt%2857%29%29%2F6...............
