The factorised given polynomial is
Step-by-step explanation:
Given that the polynomial
To factorise the given polynomial :
Let f(x) be the given polynomial
By using the Factor theorem here
- Put x=1 in the polynomial f(x) we get
Therefore x-1 is a factor and it satisfies the given polynomial.( by factor theorem )
- Put x=10 in f(x)
Therefore x-10 is a factor and it satisfies the given polynomial.( by factor theorem )
- Put x=12 in f(x)
Therefore x-12 is a factor and it satisfies the given polynomial.( by factor theorem )
Therefore the factors are x-1,x-10,x-12
