Solved the equation \(2x^2 – x – 6\) = 0
-
x = \(\frac{-3}{2}\) or 2
- x = -2 or \(\frac{3}{2}\)
- x = -3 or 2
- x = 3 or -2
The correct answer is: A
Explanation
\(2x^2 - x - 6\) = 0
\(2x^2 - 4x + 3x - 6\) = 0
2x(x - 2) + 3(x - 2) = 0
(2x + 3) (x - 2) = 0
Either; 2x + 3 = 0 or x - 2 = 0
x = \(\frac{-3}{2}\) or x = 2
