Answer 1

first notice the last digit of the polynomial then find the factor of the last digit number if zero will come in any of the factor then it is the zeroes of polynomial subtracting x- to the zeroes we get factor of the polynomial.divide the cubic polynomial with that factor. after dividing we get a quadratic polynomial.then factorise that polynomial by middle term spilt method.the other two factor will be shown .in this way we can factorise a cubic polynomial...
