Expand and Simplify (2x+3)(3x-3)

First, take the 2x and multiply each term in the second bracket by it to give 2x.3x=6x² and 2x.-3= -6x. Then multiply each term of the second bracket by +3 to give 3.3x= 9x and 3.-3=-9 . adding all the terms we now have together gives 6x²-6x+9x-9as there is a +9x and -6x gives 3x so now the simplified equation is 6x²+3x-9
