Solve x^2 = −5x − 3 → x^2 + 5x + 3 = 0. Use quadratic formula:
x = [−5 ± √(25 − 12)]/2 = [−5 ± √13]/2.
So the correct choice is: StartFraction negative 5 minus StartRoot 13 EndRoot Over 2 EndFraction , StartFraction negative 5 + StartRoot 13 EndRoot Over 2 EndFraction (i.e. (−5 ± √13)/2).
x = [−5 ± √(25 − 12)]/2 = [−5 ± √13]/2.
So the correct choice is: StartFraction negative 5 minus StartRoot 13 EndRoot Over 2 EndFraction , StartFraction negative 5 + StartRoot 13 EndRoot Over 2 EndFraction (i.e. (−5 ± √13)/2).
