1 answer

To solve the equation \( x^2 - 2x + 2 - 3x - x = 0 \), we first simplify the equation.

Combine the like terms:

\[ x^2 - 2x - 3x - x + 2 = 0 \] \[ x^2 - 6x + 2 = 0 \]

Now we can use the quadratic formula \( x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \).

In this case, \( a = 1 \), \( b = -6 \), and \( c = 2 \).

Calculate the discriminant:

\[ b^2 - 4ac = (-6)^2 - 4(1)(2) = 36 - 8 = 28 \]

Now substitute \( a \), \( b \), and the discriminant into the quadratic formula:

\[ x = \frac{-(-6) \pm \sqrt{28}}{2(1)} = \frac{6 \pm \sqrt{28}}{2} \]

We can simplify \( \sqrt{28} \):

\[ \sqrt{28} = \sqrt{4 \cdot 7} = 2\sqrt{7} \]

Substituting back into the formula:

\[ x = \frac{6 \pm 2\sqrt{7}}{2} \]

This can be simplified further:

\[ x = 3 \pm \sqrt{7} \]

Thus, the two solutions are:

\[ x_1 = 3 + \sqrt{7} \] \[ x_2 = 3 - \sqrt{7} \]

Since we want the smaller value first:

The answers are: \[ x = 3 - \sqrt{7} \quad \text{and} \quad x = 3 + \sqrt{7} \]

So the final boxed answer should be:

Smaller value:

\[ 3 - \sqrt{7} \]

Larger value:

\[ 3 + \sqrt{7} \]
