I get see photo. I l ow this is wrong. Can you help?

mylen [45]

Given the equation:

$y=x^2+x-4$

We will find the value of (y) when ( x = 2i )

Note: i² = -1

so, when x = 2i

$y=(2i)^2+(2i)-4$

Simplifying the answer

So,

$\begin{gathered} y=4i^2+2i-4 \\ y=4\cdot(-1)+2i-4 \\ y=-4+2i-4 \\ y=-8+2i \end{gathered}$

So, the answer will be y = -8+2i
