Answer:
Step-by-step explanation: Let's plug in the values into the formula:
(x - (-0.011) = sqrt((0.011)^2 + 4(-0.064)) / 2
Simplifying this expression gives us:
x = 0.378 or x = 1.622
Therefore, there are two real solutions to the equation x² - 0.011x - 0.064 = 0, correct to three decimal places.
