(3+2x)*(3-2x) = 9 - 4x2

That's pretty easy. Just add the like terms (2x and 32x) and keep the 3. You get 34x plus 3.
2x + 3 = 92x = 9 - 32x = 6x = 6/2x = 3
If you mean: 32x-3x+1 then it can be simplified to 29x-1
4x - 3 = 2x + 54x - 2x = 5 + 32x = 8x = 8/2x = 4To check:4(4) - 3 = 132(4) + 5 = 13
2x-1=-32x=-3+1x=-2/2x=-1
