Answer:
3
step-by-step explanation:
given
x² + 2x + c = 0 ← in standard form
with a = 1, b = 2 and c = c
if there are no real solutions then the discriminant
b² - 4ac < 0, that is
2² - (4 × 1 × c ) < 0
4 - 4c < 0 ( subtract 4 from both sides )
- 4c < - 4
divide both sides by - 4, reversing the sign as a consequence
c > 1
hence a possible value of c is 3
