Question

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

Answer 1

The part of the quadratic formula that tells you whether the quadratic equation can be solved by factoring is b^2 - 4ac

Given 2x^2 + 7x + 3 = 0
b^2 - 4ac = (7)^2 - 4(2)(3) = 49 - 24 = 25
