X^2 - x - 6
Let's factorise. So we pick two numbers such that their product gives (-6) and
adding them up gives us (-1)
Our choice pick is -3 and 2
So we have: X^2 - 3x + 2x - 6 = 0
Factorimg we have X(X - 3) + 2( X - 3) = 0
So (X - 3) and (X + 2) are the solution to the equation.
Hence my answer is X - 3 and X + 2. None of the option applies.
