Solution
Given Equation :
- f(x) = 6x² - x - 2 = 0
☞ 6x² + 3x- 4x - 2 = 0
☞ 3x(2x+1) - 2(2x+1) = 0
☞ (3x- 2)(2x+1) = 0
Zeros of Equation :
f(x) = 3x- 2 0r f(x) = 2x+1
☞ 3x - 2 = 0 0r ☞ 2x + 1 = 0
☞ 3x = 2 0r. ☞ 2x =- 1
☞ x = 2/3 0r ☞ x = -½
Therefore, -½ and 2/3 are roots of this Quadratic Equation.
