1. \((2q+6)(q-8)+(2q+6)(5q-1)\\=(2q+6)(q-8+5q-1)\\=(2q+6)(6q-9)\)
2. \((7b-8)(b+3)+(7b-8)(3b+5)\\=(7b-8)(b+3+3b+5)\\=(7b-8)(4b+8)\)
3. \((y+1)(y-6)-(4y-2)(y+1)\\=(y+1)(y-6-4y+2)\\=(y+1)(-3y-4)\)
4. \((2q+3)^2+(4q+6)\\=(2q+3)(2q+3)+2(2q+3)\\=(2q+5)(2q+3)\)
5. \((5x+3)(x+8)+(5x+3)(2x-3)\\=(5x+3)(x+8+2x-3)\\=(5x+3)(3x+5)\)
6. \((4a+1)^2+(12a+3)\\=(4a+1)(4a+1)+3(4a+1)\\=(4a+4)(4a+1)\)
7. \((7p-4)(p+5)+(7p-4)(2p+3)\\=(7p-4)(p+5+2p+3)\\=(7p-4)(3p+8)\)
8. \((a+5)(a-4)+(4a-4)(a+5)\\=(a+5)(a-4+4a-4)\\=(a+5)(5a-8)\)
9. \((7q-8)(q-6)+(7q-8)(3q-2)\\=(7q-8)(q-6+3q-2)\\=(7q-8)(4q-8)\)
10. \((x-6)(x-2)+(5x-3)(x-6)\\=(x-6)(x-2+5x-3)\\=(x-6)(6x-5)\)
11. \((x+3)(x-6)+(4x-8)(x+3)\\=(x+3)(x-6+4x-8)\\=(x+3)(5x-14)\)
12. \((3b+1)^2-(15b+5)\\=(3b+1)(3b+1)-5(3b+1)\\=(3b-4)(3b+1)\)
