The correct Answer is:
To solve the equation \(3x^2 - 2kx + 2m = 0\) for \(k\) given that \(x = 2\) and \(m = 3\), we can follow these steps: ### Step 1: Substitute the values of \(x\) and \(m\) into the equation. We start with the equation: \[ 3x^2 - 2kx + 2m = 0 \] Substituting \(x = 2\) and \(m = 3\): \[ 3(2)^2 - 2k(2) + 2(3) = 0 \] ### Step 2: Calculate \(3(2)^2\) and \(2(3)\). Calculating \(3(2)^2\): \[ 3(2^2) = 3(4) = 12 \] Calculating \(2(3)\): \[ 2(3) = 6 \] ### Step 3: Substitute these values back into the equation. Now substituting these values back into the equation gives us: \[ 12 - 4k + 6 = 0 \] ### Step 4: Combine like terms. Combine \(12\) and \(6\): \[ 18 - 4k = 0 \] ### Step 5: Solve for \(k\). To isolate \(k\), we can rearrange the equation: \[ -4k = -18 \] Dividing both sides by \(-4\): \[ k = \frac{18}{4} = \frac{9}{2} \] ### Conclusion: Thus, the value of \(k\) is: \[ k = \frac{9}{2} \]
