1. Problem Description

The problem is to solve the quadratic equation 2x27x+1=02x^2 - 7x + 1 = 0.

2. Solution Steps

We will use the quadratic formula to solve for xx. The quadratic formula is given by:
x=b±b24ac2ax = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}
In our equation, 2x27x+1=02x^2 - 7x + 1 = 0, we have a=2a = 2, b=7b = -7, and c=1c = 1. Substituting these values into the quadratic formula, we get:
x=(7)±(7)24(2)(1)2(2)x = \frac{-(-7) \pm \sqrt{(-7)^2 - 4(2)(1)}}{2(2)}
x=7±4984x = \frac{7 \pm \sqrt{49 - 8}}{4}
x=7±414x = \frac{7 \pm \sqrt{41}}{4}
Therefore, the two solutions are:
x=7+414x = \frac{7 + \sqrt{41}}{4}
x=7414x = \frac{7 - \sqrt{41}}{4}

3. Final Answer

The solutions to the equation are x=7+414x = \frac{7 + \sqrt{41}}{4} and x=7414x = \frac{7 - \sqrt{41}}{4}.
