Factor the polynomial completely Px9x216 PXMy answer and it
Factor the polynomial completely.
P(x)=9x^2+16
P(X)=____________My answer and it is wrong. 9x2+16
Find all its zeros. State the multiplicity of each zero. (If an answer does not exist, enter DNE.)
| real zero ____(can\'t find this answer) | with multiplicity | DNE | ||||
| complex zero | 4/3 i | (positive imaginary part) | with multiplicity | 2 | ||
| complex zero | 4/3 i | (negative imaginary part) | with multiplicity 2 |
Solution
p(x) = 9x^2 + 16
to factor the polynomial we need two such factors of 9*16 that is 144 that will add up to become 0
there are no such factors that adds up to become zero
hence this polynomial cannot be factored
it is prime polynomial
zeros of the polynomial are
9x^2+16 = 0
9x^2 = -16
x^2 = -16/9
x = + - 4/3 i
therefore , zeros of polynomial are
+ 4/3 i with multiplicity 1
- 4/3 i with multiplicity 1
