Answer:
+ or - square root of 5, and + or - i
Step-by-step explanation:
(x^2 + 5)(x^2 + 1)= 0
Set each set of parentheses equal to zero:
x^2 + 5 = 0; x^2 = -5, so x will equal plus or minus i times the square root of 5.
X^2 +1 = 0; x^2 = -1, so x will equal plus or minus i times the square root of one, which is just i
Answer: The solutions are i and 5i.
Step-by-step explanation:
Since we have given that
By using Substitution, we use
in the above equation:
Now, put the value of y in the equation .
Put y = -1,
Similarly, put y = -5
Hence, the solutions are i and 5i.
