To solve for \( k \) in the equation \( 3 k^{2} - 10 k + 8 = 0 \), we can use the quadratic formula, which states: \[ k = \frac{{-b \pm \sqrt{{b^2 - 4ac}}}}{2a} \] Here, the coefficients are: - \( a = 3 \) - \( b = -10 \) - \( c = 8 \) First, we calculate the discriminant: \[ b^2 - 4ac = (-10)^2 - 4(3)(8) = 100 - 96 = 4 \] Now, substituting \( a \), \( b \), and the discriminant into the quadratic formula: \[ k = \frac{{-(-10) \pm \sqrt{4}}}{2 \times 3} = \frac{{10 \pm 2}}{6} \] This gives us two potential solutions: 1. \( k = \frac{{10 + 2}}{6} = \frac{12}{6} = 2 \) 2. \( k = \frac{{10 - 2}}{6} = \frac{8}{6} = \frac{4}{3} \) Thus, the solutions for \( k \) are: \[ k = 2 \quad \text{and} \quad k = \frac{4}{3} \]
