Replace f(x) with 0 and swith the equation around to solve for x
x^4 - 32x^2 - 144 = 0
Factor the left side:
(x+6) (x-6) (x^2+4)
so far we have x+6 = 0, x = -6
x -6 = 0, x = 6
solve x^2 +4 = 0
x^2 = -4
x = sqrt(-4)
x = 2i, -21
The answer is B) 2i, 6, -6
a) 2/5(n)=6 n=15
b) 4/7(x)=16/3 x=28/3 x=9.33333 x=9 1/3
any option for b works
i hope this is right and helps
Answer:
4
4+4-4=4 im not sure actually D:
12 - b = -2
12 + 2 = b
14 = b
