Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring. 

            −b             b2 − 4ac            2a 

Use the part of the quadratic formula that you chose above and find its value given the following quadratic equation: 

2x2 + 7x + 3 = 0

calculusxy · Answer

The discriminant, b² - 4ac, is the answer. If b² - 4ac = 0, then the solution to the equation boils down to x = (-b ± 0)/2a = -b/2a, and there is only one solution to the equation, which means the equation cannot be factored by ordinary means.

2x² + 7x + 3 = 0

b² - 4ac = (7)² - 4(2)(3) = 49 - 24 = 25.
