Answer:

The value of x is -2 and 2.

Step-by-step explanation:

When solve an expression, you have to make the expression equals to 0 by moving all the terms to one side :

x² - 3x - 1 = -3x + 3

x² - 3x - 1 + 3x - 3 = 0

x² - 4 = 0

Next, you have to factorize and solve it :

x² - 4 = 0

x² + 2x - 2x - 4 = 0

x(x + 2) - 2(x + 2) = 0

(x + 2)(x - 2) = 0

x + 2 = 0

x = -2

x - 2 = 0

x = 2

ahrayia [7]
You need the compound interest formula solved for time:
Years = log (total / principal) / n * log (1 + rate / n)
Years = log (9,000 / 5,960.32) / 2 * log (1 + .042/2)
Years = log ( <span> <span> <span> 1.509986041</span></span></span>) / 2 * log (1.021)
Years =  0.1789729325 / 2 * 0.0090257420869
Years =  <span> <span> </span></span><span><span><span>0.1789729325 / 0.0180514842 </span> </span> </span>
<span><span><span>Years =  9.9145826746 </span> </span> </span>
