1. \((6a-5)(a+3)-(6a-5)(5a-9)\\=(6a-5)(a+3-5a+9)\\=(6a-5)(-4a+12)\)
2. \((3q-6)(q-1)-(3q-6)(2q+4)\\=(3q-6)(q-1-2q-4)\\=(3q-6)(-q-5)\)
3. \((y-2)(y+3)-(3y+5)(y-2)\\=(y-2)(y+3-3y-5)\\=(y-2)(-2y-2)\)
4. \((b+6)(b-7)+(2b+3)(b+6)\\=(b+6)(b-7+2b+3)\\=(b+6)(3b-4)\)
5. \((3p-8)(p+7)-(3p-8)(5p+3)\\=(3p-8)(p+7-5p-3)\\=(3p-8)(-4p+4)\)

7. \((6a-5)^2+(24a-20)\\=(6a-5)(6a-5)+4(6a-5)\\=(6a-1)(6a-5)\)
8. \((7b-4)(b+9)+(7b-4)(3b+3)\\=(7b-4)(b+9+3b+3)\\=(7b-4)(4b+12)\)
9. \((3p-8)(p-9)-(3p-8)(4p+2)\\=(3p-8)(p-9-4p-2)\\=(3p-8)(-3p-11)\)
10. \((q+4)(q+1)-(4q+1)(q+4)\\=(q+4)(q+1-4q-1)\\=(q+4)(-3q+0)\)
11. \((a-2)(a+8)-(2a-1)(a-2)\\=(a-2)(a+8-2a+1)\\=(a-2)(-a+9)\)
12. \((3p-9)(p+6)+(3p-9)(4p-6)\\=(3p-9)(p+6+4p-6)\\=(3p-9)(5p+0)\)
