You must use quadratic formula for each. 

The term in front of the x^{2} is the "a" value in the quadratic formula. The term in front of the x is the "b" value. And the constant term (no x's) is the "c" value. Now you must simply substitute these values into the quadratic formula for each question.

1.) x = -0.268 and x = -3.732

2.) x = -0.838 and x = -7.16

3.) x = 3.56 and x = -0.561

4.) x = 6.70 and x = 0.298

Hope this helps!

Sound level is measured in <u>  decibels  </u> (dB).

The equation \beta = 10\log\left(\frac{I}{I_0}\right), where I_0 is the intensity of the <u>   threshold  </u> sound a human can hear (10^{-12} \text{watts}/\text{meter}^2) and I is the <u>   intensity    </u> of the sound being measured, gives the sound level, \beta

Example:

What was the intensity of the launch of NASA's Saturn V rocket, about 200 dB?

\beta = 10\log\left(\frac{I}{I_0}\right)\\\\\text{Substitute.} \ 200 = 10\log\left(\frac{I}{10^{-12}}\right)\\\\\text{Isolate the log.} \ 20 = \log\left(\frac{I}{10^{-12}}\right)\\\\\text{Rewrite into exponential form.} \ \frac{I}{10^{-12}} = 10^{20}\\\\\text{Solve for the variable}\\ \ I = (10^{20})(10^{-12}) = 10^8 = 100,000,000 = \text{100 million watts/}m^2
