Question

If the polynomial function P has real coefficients and if a + bi is a zero of P, then Incorrect:________

Answer 1

Answer:

• a -bi
• 2 -i

Step-by-step explanation:

If a polynomial has real coefficients, complex zeros come in conjugate pairs.

If a+bi is a zero, then so is a-bi. (a-bi is the conjugate of a+bi)

If 2+i is a zero, then so is 2-i.
