Question 391585
2x^2 + x + 3= 

you have to find the roots of the equation.
product of first term co-efficient & third term = 6
..
split 6 into two parts such that the product of the parts is 6 and the sum of the parts is +1 (1x) the middle term

..
In this expression the roots are complex numbers and hence cannot be factored without the quadratic expression.
