The correct Answer is:
To determine whether the statement "The discriminant of \((x-2)^2 = 0\) is positive" is true or false, we will first rewrite the equation in standard form and then calculate the discriminant. ### Step 1: Rewrite the equation The given equation is \((x-2)^2 = 0\). We can expand this using the identity \((a-b)^2 = a^2 - 2ab + b^2\). \[ (x-2)^2 = x^2 - 4x + 4 = 0 \] ### Step 2: Identify coefficients From the standard form of the quadratic equation \(ax^2 + bx + c = 0\), we can identify the coefficients: - \(a = 1\) - \(b = -4\) - \(c = 4\) ### Step 3: Calculate the discriminant The discriminant \(D\) of a quadratic equation is given by the formula: \[ D = b^2 - 4ac \] Substituting the values of \(a\), \(b\), and \(c\): \[ D = (-4)^2 - 4 \cdot 1 \cdot 4 \] \[ D = 16 - 16 \] \[ D = 0 \] ### Step 4: Analyze the result Since the discriminant \(D\) is equal to 0, it indicates that the quadratic equation has two identical roots. ### Conclusion The statement "The discriminant of \((x-2)^2 = 0\) is positive" is **false** because the discriminant is 0, not positive. ---
