Hope I helped :)
Answer:
x=2, -4, -1
Step-by-step explanation:
-x³-3x²+6x+8=0
Multiply entire equation by -1:
x³+3x²-6x-8=0
Since x=2 is a solution, then x-2 must be a factor. Then:
x³+3x²-6x-8/x-2=x²+5x+4
x²+5x+4=0
Factor this:
x²+5x+4=(x+4)(x+1)=0
x=-4, -1
x=2, -4, -1
The probability of choosing a red hat is 7/15
<h3>How to determine the probability?</h3>
The given parameters are:
Red = 14
Blue = 16
The probability of red is calculated as:
P(Red) = Red/Total
This gives
P(Red) = 14/30
Simplify
P(Red) = 7/15
Hence, the probability of choosing a red hat is 7/15
