Find the roots of the quadratic equation 6x2 - x - 2 = 0
Solution:
Let us find the roots of the quadratic equation by splitting the middle term.
⇒ 6x2 - x - 2 = 0
Split bx into such a way that it is equal to a×c
- 1x can be split into - 4 and 3. [ ∵ (- 4) × (3) = 12].
⇒ 6x2 - x - 2 = 0 can be written as
⇒ 6x2 + 3x - 4x - 2 = 0
Taking out the common factors
⇒ 3x (2x + 1) - 2(2x + 1)
⇒ (2x + 1)(3x - 2)
Put the both the factors equal to 0
⇒ 2x + 1 = 0 and 3x - 2 = 0.
⇒ x = -1/2 and x = 2/3 are the solutions of the equation
The roots of the equation 6x2 - x - 2 = 0 are 2/3 and - 1/2 which satisfies the equation
