1. \((3y+6)(y-4)+(3y+6)(4y-4)\\=(3y+6)(y-4+4y-4)\\=(3y+6)(5y-8)\)
2. \((3q-7)(q+8)-(3q-7)(2q+1)\\=(3q-7)(q+8-2q-1)\\=(3q-7)(-q+7)\)
3. \((3p-9)(p-8)-(3p-9)(4p-8)\\=(3p-9)(p-8-4p+8)\\=(3p-9)(-3p+0)\)
4. \((6s+1)^2+(24s+4)\\=(6s+1)(6s+1)+4(6s+1)\\=(6s+5)(6s+1)\)
5. \((x-5)(x-2)-(4x+2)(x-5)\\=(x-5)(x-2-4x-2)\\=(x-5)(-3x-4)\)
6. \((5y-3)(y+2)+(5y-3)(4y-8)\\=(5y-3)(y+2+4y-8)\\=(5y-3)(5y-6)\)
7. \((6p-5)^2+(12p-10)\\=(6p-5)(6p-5)+2(6p-5)\\=(6p-3)(6p-5)\)
8. \((b+4)(b+9)+(5b+1)(b+4)\\=(b+4)(b+9+5b+1)\\=(b+4)(6b+10)\)
9. \((y+3)(y-4)+(2y+6)(y+3)\\=(y+3)(y-4+2y+6)\\=(y+3)(3y+2)\)
10. \((3p+8)(p-6)+(3p+8)(2p+5)\\=(3p+8)(p-6+2p+5)\\=(3p+8)(3p-1)\)
11. \((3x+7)(x-6)-(3x+7)(2x-1)\\=(3x+7)(x-6-2x+1)\\=(3x+7)(-x-5)\)
12. \((x+4)(x-6)+(2x-7)(x+4)\\=(x+4)(x-6+2x-7)\\=(x+4)(3x-13)\)
