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.
General formula for area of triangle is 
.
Where:
is height of triangle perpendicular to base side of triangle.
is the length of base side of triangle.
Multiplying and results in rectangle, dividing that by 2 gives you area of a triangle.
