The left hand side expression of the given equation is a difference of two squares. The first term, x², is a square of x and the second term, 25 is the square of 5. The factors of the expression are (x - 5) and (x + 5).
(x - 5)(x + 5) = 0
The values of x from the equation above are x = -5 and x = 5.
Answer:
488 meters above sea level.
Step-by-step explanation:
Since the difference between that point and the tallest point is 1,232 you need to subtract 1,232 - 12 = 1,220 to get how far Mt ka'ala is from sea level. Since the ranger station is 2/5 up the mountain you can do 1,220/5 = 244. This is 1/5 of the way up the mountain. Then you do 244 x 2 = 488. That is 2/5 up the mountain. Final answer: The ranger station is 488 meters above sea level.

Putting values
If the roots are r1,r2,r3, the facotred polynomail looksl ike this
f(x)=(x-r1)(x-r2)(x-r3)
given
roots 4,2i and -2i
f(x)=(x-4)(x-2i)(x-(-2i))
f(x)=(x-4)(x-2i)(x+2i)
expand
f(x)=x³-4x²+4x-16
