Which method is MOST EFFICIENT to solve:
5x²  -3x - 7  = 0

• Square Root Method

• Factoring

• Complete the Square

• Quadratic Formula

• a = 2 , b = 3, c = -5

• a = 2, b = -3, c = 5

• a = 2, b = -3, c = -5

• a = -2, b = 3, c = 5

If there are no real solutions, the discriminant is

• zero

• a postive number

• a negative number

• a perfect square
