The geometric mean of two numbers is the square root of their product:

So, if the product is 8, the geometric mean is 
A positive number
This is because you must add to get from a negative number in order to get to a positive number.
Answer:
yes
Step-by-step explanation:
take for example
in the expression: 3x²+5x+2=0,
the coefficients here are +3 and +5 while +2 is a constant. +3 and +5 are coefficients of the variables x² and x respectively
B. 12 would be your answer
