= 576
So, the answer is 576
The value -0.07 is the negative real number in the quadratic equation 0 = x² – 5x – 4
Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.
As we know, the formula for the roots of the quadratic equation is given by:
We have a quadratic equation;
0 = x² – 5x – 4 or
x² – 5x – 4 = 0
Here a = 1, b = -5, and c = -4
After simplification:
x = 5.70 or x = -0.70
The value x = -0.70 is the negative real number.
Thus, the value -0.07 is the negative real number in the quadratic equation 0 = x² – 5x – 4

Step-by-step explanation:
Given
The difference in population
The population of China is 0.2 million times greater than the population of Julie's hometown.
To find out how many times greater the population of China is than Julie's hometown, we can set up a ratio using scientific notation:
Population of China = 1.4 x 10⁹
Population of Julie's hometown = 7,000 = 7 x 10³
Ratio = Population of China / Population of Julie's hometown
Ratio = (1.4 x 10⁹) / (7 x 10³)
Now, divide the numbers and subtract the exponents of 10:
Ratio =
Ratio = 0.2 x 10⁶
So, the population of China is 0.2 million times greater than the population of Julie's hometown.
