The correct Answer is:
To solve the quadratic equation \(2x^2 - x + \frac{1}{8} = 0\), we will follow these steps: ### Step 1: Eliminate the Fraction To eliminate the fraction, we can multiply the entire equation by 8 (the denominator). \[ 8(2x^2) - 8(x) + 8\left(\frac{1}{8}\right) = 0 \] This simplifies to: \[ 16x^2 - 8x + 1 = 0 \] ### Step 2: Identify Coefficients Now, we can identify the coefficients \(a\), \(b\), and \(c\) from the standard form of a quadratic equation \(ax^2 + bx + c = 0\). Here, we have: - \(a = 16\) - \(b = -8\) - \(c = 1\) ### Step 3: Use the Quadratic Formula We can use the quadratic formula to find the roots of the equation, which is given by: \[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] ### Step 4: Calculate the Discriminant First, we calculate the discriminant \(D = b^2 - 4ac\): \[ D = (-8)^2 - 4(16)(1) = 64 - 64 = 0 \] ### Step 5: Calculate the Roots Since the discriminant is 0, we have real and equal roots. Now, substituting the values into the quadratic formula: \[ x = \frac{-(-8) \pm \sqrt{0}}{2(16)} = \frac{8 \pm 0}{32} = \frac{8}{32} = \frac{1}{4} \] ### Step 6: Conclusion Thus, the roots of the equation are: \[ x = \frac{1}{4} \quad \text{(with multiplicity 2)} \]

To solve the quadratic equation \(2x^2 - x + \frac{1}{8} = 0\), we will follow these steps: ### Step 1: Eliminate the Fraction To eliminate the fraction, we can multiply the entire equation by 8 (the denominator). \[ 8(2x^2) - 8(x) + 8\left(\frac{1}{8}\right) = 0 \] ...
