1. \((4x-3)(x-6)-(4x-3)(5x-8)\\=(4x-3)(x-6-5x+8)\\=(4x-3)(-4x+2)\)
2. \((8s+7)(s+2)-(8s+7)(5s-1)\\=(8s+7)(s+2-5s+1)\\=(8s+7)(-4s+3)\)
3. \((7q+1)^2-(35q+5)\\=(7q+1)(7q+1)-5(7q+1)\\=(7q-4)(7q+1)\)
4. \((3b-2)^2+(9b-6)\\=(3b-2)(3b-2)+3(3b-2)\\=(3b+1)(3b-2)\)
5. \((2y+4)(y-1)-(2y+4)(3y+8)\\=(2y+4)(y-1-3y-8)\\=(2y+4)(-2y-9)\)
6. \((5y+1)(y+2)+(5y+1)(2y-6)\\=(5y+1)(y+2+2y-6)\\=(5y+1)(3y-4)\)
7. \((3y+5)(y-5)+(3y+5)(2y-6)\\=(3y+5)(y-5+2y-6)\\=(3y+5)(3y-11)\)
8. \((2x-6)(x-4)-(2x-6)(5x-1)\\=(2x-6)(x-4-5x+1)\\=(2x-6)(-4x-3)\)
9. \((5x+6)(x+1)-(5x+6)(3x+4)\\=(5x+6)(x+1-3x-4)\\=(5x+6)(-2x-3)\)
10. \((2p-5)(p+1)-(2p-5)(5p-1)\\=(2p-5)(p+1-5p+1)\\=(2p-5)(-4p+2)\)
11. \((8p+3)^2-(40p+15)\\=(8p+3)(8p+3)-5(8p+3)\\=(8p-2)(8p+3)\)
12. \((8b+7)^2-(24b+21)\\=(8b+7)(8b+7)-3(8b+7)\\=(8b+4)(8b+7)\)
