Decide which part of the quadratic formula tells you whether the quadratic equation can be solved by factoring.

Question

−b b^2 − 4ac 2a

Use the part of the quadratic formula that you chose above and find its value, given the following quadratic equation:

4x^2 + 6x + 2 = 0

Answer 1

can be solved by factoring. ??

I wonder if your teacher meant "can have real roots". All can be factored, however, if the (b^2-4ac) is negative, the roots are complex, and Difficult to factor, however, they can be solved by factoring.

b^2-4ac
36-34...=4

Answer 2
