Given that,
➢ Sum of the zeroes : α + ß = 2
➢ Product of the zeroes : αß = -3/5
General form of quadratic polynomial is,
⟹ x² - (α + ß)x + αß = 0
➡ x² -(2)x + ( -3/5 ) = 0
➡ x² - 2x - 3/5 = 0
- By taking LCM as 5, we get..
➡ 5x² - 10x - 3 = 0
Therefore, the quadratic polynomial is 5x² - 10x - 3 = 0
