Step-by-step explanation:
letp(x) x³-4x²+x+6
here 6= 1×2×3=> (x±1),(x±2),(x±3) may be factors of the polynomial.
checking for x-1 =0=> x= 1 then
p(1)= 1³-4×1¹+1+6≠0
=> x-1 is not a factor
again if x+1 is a factor=> x+1=0> x= -1
=> p(-1) = -1³-1²×4-1+6=0
=> x+1 is factor of p(x)
similarly if x-2 is a factor=> p(2) = 8-16-2+6=0
=> x-2 is a factor of p(x)
again if x+2 is a factorthen p(-2) ≠0
if x-3 is a factor p(3)= 27-36+3+6= 26-36=0
=> x-3 is a factor of p(x)
hence x³-4x²+x+6= (x+1)(x-2) (x-3)
Hope this helps you better than your hope
