Answer:
That is correct
Step-by-step explanation:
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.
I believe that you are supposed to use Lower Case Roman Numerals
You would write the ration as 6:8. ratios are written as (blank):(blank) the blanks being the numbers and the : representing to. so for every 6 hearts you have 8 starts. 6:8.
