Take the factors of 12 as +_1 +_2 +_3 +_4 +_5 +_6..........
put the value of x as-1 and then solve it which will leave 0 as remainder now through long division method solve it. take that long term as divident and x+1 as divisor and solve it this will give u p(x) =
now take the commons
(x+1)(x-3)(x² - 4 ) are the factors...
