Solve each quadratic equation by completing the square. Give exact answers--no decimals.
denis-greek [22]

Answer:

x_1 = \frac{3}{2} + \frac{1}{2}(\sqrt{47})i\\\\x_2 = \frac{3}{2} - \frac{1}{2}(\sqrt{47})i\\\\

Step-by-step explanation:

In this problem we have the equation of the following quadratic equation and we want to solve it using the method of square completion:

x ^ 2 -3x +14 = 0

The steps are shown below:

For any equation of the form: ax ^ 2 + bx + c = 0

1. If the coefficient a is different from 1, then take a as a common factor.

In this case a = 1.

Then we go directly to step 2

2. Take the coefficient b that accompanies the variable x. In this case the coefficient is -3. Then, divide by 2 and the result squared it.

We have:

\frac{-3}{2} = -\frac{3}{2}\\\\(-\frac{3}{2}) ^ 2 = (\frac{9}{4})

3. Add the term obtained in the previous step on both sides of equality:

x ^ 2 -3x + (\frac{9}{4}) = -14 + (\frac{9}{4})

4. Factor the resulting expression, and you will get:

(x -\frac{3}{2}) ^ 2 = -(\frac{47}{4})

Now solve the equation:

Note that the term (x -\frac{3}{2}) ^ 2 is always > 0 therefore it can not be equal to -(\frac{47}{4})

The equation has no solution in real numbers.

In the same way we can find the complex roots:

(x -\frac{3}{2}) ^ 2 = -(\frac{47}{4})\\\\x -\frac{3}{2} = \±\sqrt{-(\frac{47}{4})}\\\\x  = \frac{3}{2} \±\frac{1}{2}\sqrt{-47}\\\\x = \frac{3}{2} \±\frac{1}{2}(\sqrt{47})i\\\\x_1 = \frac{3}{2} + \frac{1}{2}(\sqrt{47})i\\\\x_2 = \frac{3}{2} - \frac{1}{2}(\sqrt{47})i\\\\
