Use the quadratic formula to solve the equation.<br><br>-3x^2 - x - 3 = 0
vredina [299]

Answer:  -1 ± <em>i</em>√35

                  ⁻⁻⁻⁻⁻⁻⁻⁻

                     6

Step-by-step explanation:

From the quadratic equation,

X =  -b ±√b² - 4ac

     ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻

             2a

From the given equation, -3x² - x - 3 = 0

where a = -3, b = -1, c = -3

Now substitute for the values in the formula above

x = -(-1) ± √(-1)² - 4(-3)(-3)

      ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻

                   2(-3)

x = 1 ± √ 1 - 36

     ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻

           -6

x = 1 ±  √ -35

     ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻

           -6

x = -1  ±  <em>i√35   this is because it has a negative root.</em>

<em>       ⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻⁻</em>

<em>            6</em>

<em> The answer is b</em>

Using the quadratic formula to solve 11x^2-4x=1, what are the values of X?
Rashid [163]
The correct answers for x would be \frac{2 +/-  \sqrt{15} }{11}.

In order to find this, we must first get the equation to equal 0. In order to do that, subtract 1 from each side to get the following. 

11x^{2} - 4x - 1 = 0

Knowing this we can now use the quadratic equation using a = 11, b = -4 and c = -1. The quadratic equation is below. 

\frac{-b +/-  \sqrt{ b^{2} - 4ac} }{2a}

Now we can plug the values into the equation to solve. 

\frac{4 +/- \sqrt{ -4^{2} - 4(11)(-1)} }{2(11)}

Then simplify using the order of operations. 

 \frac{2 +/- \sqrt{15} }{11}.
