Answer:
and
Step-by-step explanation:
We have to solve the given equation - 2x² + 3x - 9 = 0
To solve the equation given above we have to factorize the left-hand side of the equation.
But it can not be factorized. So, use the Sridhar Achaya formula.
Therefore, and
So, and {Where }
Therefore, the solutions are imaginary numbers. (Answer)
Note: The Sridhar Acharya Formula gives if ax² + bx + c = 0, then the roots of the equation are and .
