Question

if 3 & -3 are two zeros of the polynomials P(x) = x4 + x3-11x2 - 9x + 18
X+X-11X-9x+18, then find the remaining two zeros.​

Answer 1

Answer:

Step-by-step explanation:

A polynomial of degree n can have atmost n zeroes.  

Ex. -Take a polynomial (3x²-2x+6). As we can see here, the degree of this polynomial is 2. We have learnt that a polynomial can have atmost that no. of zeroes, of which it has  degree. It means that this polynomial will have atmost 2 zeroes.  

Similarly, a polynomial having degree n can have atmost n zeroes.
