6 x^{2} +5x-6

Factorisation:
coefficient of 
 x^{2} ×constant     
× - 6 = - 36
then the product of two numbers must be -36 and the sum must be -5  
as -9 
× 4 = 36 and (-9) + 4 = - 5
so 
 6x^{2} + (-9 +4) x -6
 6x^{2} -9x + 4x -6
then , 3x (2x -3) +2 (2x -3)
i.e 
 6x^{2}  + 5x -6 = (3x+2) and (2x-3)

therefore the factors of 
6 x^{2} +5x -6 are (3x+2) & (2x-3)

Hope this may helps uu..............
