Answer:

The solution of given equation for x is  (0.16 + i 1.14) , (0.16 - i 1.14)  

Step-by-step explanation:

Given as :

The quadratic equation is as 3 x² - x + 4 = 0

Since The given equation is quadratic

∵, Standard quadratic equation is ax² + bx + c = 0

Now, x = \frac{-b\pm \sqrt{b^{2} - 4\times a\times c}}{2\times a}

<u>Comparing the equation</u>

i.e x = \frac{-(-1)\pm \sqrt{(-1)^{2} - 4\times 3\times 4}}{2\times 3}

or, x = \dfrac{1\pm \sqrt{(1-48)}}{6}

Or, x = \dfrac{1\pm \sqrt{(-47)}}{6}

Or, x = \dfrac{1\pm i6.85}{6}

Or, x = (0.16 + i 1.14)   , (0.16 - i 1.14)

So, The solution of given equation for x = (0.16 + i 1.14)   , (0.16 - i 1.14)

Hence, The solution of given equation for x is  (0.16 + i 1.14) , (0.16 - i 1.14)  . Answer
