d and e

Step-by-step explanation:

Use the quadratic formula to solve for this.

$\frac{-b +-\sqrt{b^2 - 4ac} }{2a}$ ( opposite b, plus or minus, the square root of b squared minus 4 times a times c)

x^2 + 3x + 5

1 = a

3 = b

5 = c

-3 +- $\sqrt{3^2 - 4(1)(5)}$

2(1)

3^2 - 4(1)(5) = --11

sqrt of -11 could be reduced to $i\sqrt{11}$

so your answer would be:

$\frac{-3 + i\sqrt{11} }{2} \frac{-3 - i\sqrt{11}}{2}$
