The correct Answer is:
To find the quadratic equation with roots \(5\) and \(-2\), we can follow these steps: ### Step 1: Identify the roots The roots of the quadratic equation are given as \(5\) and \(-2\). ### Step 2: Calculate the sum of the roots The sum of the roots \(s\) can be calculated as: \[ s = 5 + (-2) = 5 - 2 = 3 \] ### Step 3: Calculate the product of the roots The product of the roots \(p\) can be calculated as: \[ p = 5 \times (-2) = -10 \] ### Step 4: Write the standard form of the quadratic equation The standard form of a quadratic equation based on its roots is given by: \[ x^2 - sx + p = 0 \] Substituting the values of \(s\) and \(p\) we found: \[ x^2 - 3x - 10 = 0 \] ### Final Answer Thus, the quadratic equation whose roots are \(5\) and \(-2\) is: \[ x^2 - 3x - 10 = 0 \] ---
