Answer:
NO
Step-by-step explanation:
If x-2 id factor of p(x)=x⁵-5x³+6x+5 then p(2)must be equal to 0
Hence,
0=2⁵-5×2³+6×2+5
0=32-5×8+12+5
0=32-45+17
0=4
But 0 is not equal to 4
Thus,x-2 is not a factor of given polynomial

Answer:
No, x-2 is not the factor of the given polynomial.
Step-by-step explanation:
If x-2 is a factor of 5 - 5x³ + 6x + 5, then by substituting the value we will get the answer '0'
→ x-2 = 0
→ x = 2
Substituting :
→ 5 - 5(2)³ + 6(2) + 5 = 0
→ 5 - 40 + 12 + 5 = 0
→ -18 ≠ 0
After substituting we should get answer as '0' but we didn't.
Therefore, x-2 is not the factor of the given polynomial.
