<h3>2 answers: choice B, choice F</h3>

Explanation:

The discriminant is

D = b^2 - 4ac

D = (-5)^2 - 4(3)(-1)

D = 25 + 12

D = 37

This means 37 is under the square root, and we know the answers are B and F due to this. Also note with these two answer choices, they are in the form \frac{-b \pm \sqrt{D}}{2a} where...

  • a = 3, so 2a = 2*3 = 6
  • b = -5, so -b = -(-5) = 5

Choices A, C, D, and E can be eliminated as the discriminant for these is D = 13.
