Answer 2

The zeros of the polynomial is $(2+2i),(2-2i)$

Step-by-step explanation:

Given : Polynomial $(x-2)^2+4$

To find : The zeros of the polynomial ?

Solution :

Open the polynomial first,

$(x-2)^2+4=x^2+4-4x+4$

$(x-2)^2+4=x^2-4x+8$

Now, to find zeros we equate to zero.

$x^2-4x+8=0$

Applying quadratic formula, $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Here, a=1, b=-4 and c=8

$x=\frac{-(-4)\pm\sqrt{(-4)^2-4(1)(8)}}{2(1)}$

$x=\frac{4\pm\sqrt{16-32}}{2}$

$x=\frac{4\pm\sqrt{-16}}{2}$

$x=\frac{4\pm 4i}{2}$

$x=\frac{4+4i}{2},\frac{4-4i}{2}$

$x=2+2i,2-2i$

Therefore, the zeros of the polynomial is $(2+2i),(2-2i)$
