The correct Answer is:
To solve the equation \(\frac{1}{(t-2)^2} = 6 + \frac{1}{t-2}\), we will follow these steps: ### Step 1: Eliminate the fractions Multiply both sides of the equation by \((t-2)^2\) to eliminate the fractions: \[ 1 = 6(t-2)^2 + (t-2) \] ### Step 2: Expand the right side Now, expand the right side of the equation: \[ 1 = 6(t^2 - 4t + 4) + (t - 2) \] \[ 1 = 6t^2 - 24t + 24 + t - 2 \] \[ 1 = 6t^2 - 23t + 22 \] ### Step 3: Rearrange the equation Rearranging the equation gives us: \[ 0 = 6t^2 - 23t + 21 \] ### Step 4: Identify coefficients Now, we can identify the coefficients \(a\), \(b\), and \(c\) from the standard form of a quadratic equation \(ax^2 + bx + c = 0\): - \(a = 6\) - \(b = -23\) - \(c = 21\) ### Step 5: Calculate the product of the roots The product of the roots \(p\) and \(q\) of the quadratic equation can be found using the formula: \[ p \cdot q = \frac{c}{a} \] Substituting the values of \(c\) and \(a\): \[ p \cdot q = \frac{21}{6} = \frac{7}{2} \] ### Final Answer Thus, the value of \(p \cdot q\) is \(\frac{7}{2}\). ---
