Answer:
- -1/2 and 3 are the roots/zeros of given quadratic equation
Explanation:
2x² - 5x - 3 = 0 ____(1)
Solving LHS :
→ 2x² - 5x - 3
→ 2x² - 6x + x - 3
→ 2x(x - 3) + (x - 3)
→ (2x + 1) (x - 3)
We get, 2x² - 5x - 3 = (2x + 1) (x - 3)
Put , 2x² - 5x - 3 = (2x + 1) (x - 3) in equation (1)
→ (2x + 1) (x - 3) = 0
→ 2x + 1 = 0 , x - 3 = 0
→ 2x = -1 , x = 3
→ x = -1/2 , x = 3
