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.

This is easy. Select different values for x to find y values.

For example, let x = 0.

y = 8x + 12

y = 8(0) + 12

y = 0 + 12

y = 12

On your table, you have x = 0 and y = 12.

Do the same using other values of x.
