More help I need lots of help mostly mentally but this too

Explanation:

If we multiply some complex number a+bi with its conjugate a-bi, then we get the real number a^2+b^2. You can use the FOIL rule to confirm that (a+bi)(a-bi) = a^2+b^2 is true. Recall that i = sqrt(-1), so i^2 = -1.

In this case, a = 4 and b = 5, so,

(a+bi)(a-bi) = a^2+b^2

(4+5i)(4-5i) = 4^2+5^2

(4+5i)(4-5i) = 41

We see that x = 4 and y = -5 must be the case.

answer is : muchas/tipicas

have a nice day!
