The Deep Dive
The discriminant \(D\) of a quadratic equation \(ax^2 + bx + c = 0\) is given by the formula \(D = b^2 - 4ac\). For the equation \(16x^2 - 3x - 14 = 0\), we have \(a = 16\), \(b = -3\), and \(c = -14\). Now, let's calculate the discriminant: \[ D = (-3)^2 - 4 \cdot 16 \cdot (-14) = 9 + 896 = 905. \] Since the discriminant is positive (\(D > 0\)), there are two distinct real solutions to the equation.
