Treat x^4 as the square of p: x^4 = p^2.
Then x^4 - 5x^2 - 36 = 0 becomes p^2 - 5p - 36 = 0.
This factors nicely, to (p-9)(p+4) = 0. Then p = 9 and p = -4.
Equating 9 and x^2, we find that x=3 or x=-3.
Equating -4 and x^2, we see that there's no real solution.
Show that both x=3 and x=-3 are real roots of x^4 - 5x^2 - 36 = 0.
A) The equation will become: 18.50 (1.005) + 18.50 (0.04)= 19.3325
Which can be rounded to 19.33
b) 18.50 (1.04)-18.50(1.005)= 0.6475
Which can be rounded to 0.65
Therefore your answer is Number 1)
The answer is G
