To solve the quadratic equation \( 6x^2 - 5x - 4 = 0 \), we can use the quadratic formula: \[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \] Here, \( a = 6 \), \( b = -5 \), and \( c = -4 \). Plugging these values into the formula gives us: \[ x = \frac{5 \pm \sqrt{(-5)^2 - 4 \cdot 6 \cdot (-4)}}{2 \cdot 6} \] Calculating: 1. \( (-5)^2 = 25 \) 2. \( 4 \cdot 6 \cdot (-4) = -96 \) so, \( 25 - (-96) = 25 + 96 = 121 \) 3. Now, \( \sqrt{121} = 11 \) Thus, we have: \[ x = \frac{5 \pm 11}{12} \] Now, let’s calculate the two possible values for \( x \): 1. \( x = \frac{5 + 11}{12} = \frac{16}{12} = \frac{4}{3} \) 2. \( x = \frac{5 - 11}{12} = \frac{-6}{12} = -\frac{1}{2} \) Arranging in order from least to greatest, we have: \( x = -\frac{1}{2} \) \( x = \frac{4}{3} \)
