Using the calculator to solve the quadratic equation given above, the roots that can be obtained is -1/2 and -5/2. Hence the answer should be C. Another way to solve this is to get the factors such that the sum is equal to the second term and the third term is the product of the factors

Sedaia [141]

x=10
