If the sum of roots of a quadratic equation is -2 and the product is 3, find the equation?
- x² + 2x + 3 = 0
- x² - 2x + 3 = 0
- x² + 2x - 3 = 0
- None of these
Explanation
For quadratic ax² + bx + c = 0:
Sum of roots = -b/a
Product of roots = c/a
Take a = 1, then:
-b = sum = -2 → b = 2
c = product = 3
So equation: x² + 2x + 3 = 0
