Step-by-step explanation:
P(x)=2x²-3x+1
----------
P(1) is the value we get when x in the polynominal replaced with 1:
- P(1)=2*1²-3*1+1=2-3+1=0, so P(1)=0
----------
P(x)=2x²-3x+1=2x²-2x-x+1=2x(x-1)-(x-1)=(x-1)(2x-1)
As per above we have two factors of P(x):
- Q(x)=x-1 or
- R(x)=2x-1
these are the first degree polynominals
