How many no real complex roots does the polynomial f (x) = x^4 - x^2- 12 have?
1 answer:
<h3>
Answer:</h3>
- 2 real roots
- 2 complex roots
<h3>
Step-by-step explanation:</h3>
f(x) factors as ...
... f(x) = (x² -4)(x² +3) = (x -2)(x +2)(x² +3)
The real roots are x = ±2.
The complex roots are x = ±i√3.

X=14 over 5 that's the answer I got when I did it on paper
Speed = Distance ÷ time
Speed upstream = 84 ÷ 7 = 12 km/h
Speed downstream = 84 ÷ 3 = 28 km/h
Speed in still water = 1/2(28 + 12) = 20 km/h
Answer: 20 km/h
