Answer: B

Step-by-step explanation:

x1,2 = - 3±√9+40 / 4 = - 3±7 / 4 = > x1 = - 3-7 / 4 = - 10/4 = - 5/2

x2 = 7-3 / 4 = 4/4 = 1

Using the Quadratic Formula, which of the following is the solution to the quadratic equation 2x2 + 3x - 5 = 0?a. x = - 5/2 x = - 1b. x = - 5/2, x = 1c. x = 5/2, x = 1d. x = 5/2, x = - 1
