Answer:
p = - 5i or p = 5i
Step-by-step explanation:
Noting
= i
Given
p² = - 25 ( take the square root of both sides )
p = ±
= ±
= ± 5i
Thus
p = - 5i or p = 5i
(8) = x +1
same thing as 8 = 1x
divide both sides by 1 and x = 8 Y= 8

Step-by-step explanation:
<u>Step 1: Define</u>
x⁴ - 3x² - 90
x = -3
<u>Step 2: Evaluate</u>
- Substitute in <em>x</em>: (-3)⁴ - 3(-3)² - 90
- Exponents: 81 - 3(9) - 90
- Multiply: 81 - 27 - 90
- Subtract: 54 - 90
- Subtract: -36
1/2 plus 1/3 is 5/6.
