Step-by-step explanation:
3 + 5i
<span>(3 - 5i)(3 + 5i) = </span>
<span>9 + 15i - 15i - 25i^2 = </span>
<span>9 - 25 * -1 = </span>
<span>9 + 25 = </span>
<span>34 </span>
<span>or </span>
<span>x = 3 + 5i </span>
<span>x - 3 - 5i = 0 </span>
<span>x = 3 - 5i </span>
<span>x - 3 + 5i = 0 </span>
<span>(x - 3 - 5i)(x - 3 + 5i) = 0 </span>
<span>x^2 - 3x + 5xi - 3x + 9 - 15i - 5xi + 15i - 25i^2 = 0 </span>
<span>x^2 - 6x + 34 = 0
Answer= 3+5i</span>
