#(2x-3)(x-2)=-12x+18#

Expand using the foil method.

#2x^2-4x-3x+6=-12x+18#

#2x^2-7x+6=-12x+18#

Add #12x# and subtract #18# on both sides...

#2x^2-7x+6+12x-18=0#

#2x^2+5x-12=0#

Factorise...

#(2x-3)(x+4)=0#

When #x=3/2# and #x=-4#, what you get is #0#.

Therefore, the answers are:

#x=3/2#

#x=-4#
