The correct Answer is:
To find the zeros of the polynomial \( p(x) = 4x^2 - 12x + 9 \), we will use the quadratic formula. The standard form of a quadratic polynomial is given by: \[ p(x) = ax^2 + bx + c \] Here, we identify the coefficients: - \( a = 4 \) - \( b = -12 \) - \( c = 9 \) ### Step 1: Calculate the Discriminant The discriminant \( D \) is calculated using the formula: \[ D = b^2 - 4ac \] Substituting the values of \( a \), \( b \), and \( c \): \[ D = (-12)^2 - 4 \cdot 4 \cdot 9 \] Calculating \( D \): \[ D = 144 - 144 = 0 \] ### Step 2: Determine the Roots Since the discriminant \( D = 0 \), this indicates that there are two equal roots. The roots can be calculated using the formula: \[ x = \frac{-b \pm \sqrt{D}}{2a} \] Substituting the values of \( b \), \( D \), and \( a \): \[ x = \frac{-(-12) \pm \sqrt{0}}{2 \cdot 4} \] Calculating the roots: \[ x = \frac{12 \pm 0}{8} = \frac{12}{8} = \frac{3}{2} \] ### Conclusion Thus, the two zeros of the polynomial \( p(x) = 4x^2 - 12x + 9 \) are: \[ \alpha = \beta = \frac{3}{2} \]
