Sticky Note
If the sum of roots of a quadratic equation is -2 and the product is 3, find the equation?
  1. x² + 2x + 3 = 0
  2. x² - 2x + 3 = 0
  3. x² + 2x - 3 = 0
  4. 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
