1. \((s+2)(s+2)-(2s-8)(s+2)\\=(s+2)(s+2-2s+8)\\=(s+2)(-s+10)\)
2. \((s+6)(s+3)+(3s-8)(s+6)\\=(s+6)(s+3+3s-8)\\=(s+6)(4s-5)\)
3. \((8q+7)(q+9)+(8q+7)(3q+6)\\=(8q+7)(q+9+3q+6)\\=(8q+7)(4q+15)\)
4. \((3q+2)^2+(15q+10)\\=(3q+2)(3q+2)+5(3q+2)\\=(3q+7)(3q+2)\)
5. \((5b-4)^2-(20b-16)\\=(5b-4)(5b-4)-4(5b-4)\\=(5b-8)(5b-4)\)
6. \((4q-3)(q-3)-(4q-3)(5q+3)\\=(4q-3)(q-3-5q-3)\\=(4q-3)(-4q-6)\)
7. \((b-3)(b+4)-(3b+8)(b-3)\\=(b-3)(b+4-3b-8)\\=(b-3)(-2b-4)\)
8. \((p-5)(p-4)+(5p+4)(p-5)\\=(p-5)(p-4+5p+4)\\=(p-5)(6p+0)\)
9. \((5x+7)(x+8)+(5x+7)(2x-1)\\=(5x+7)(x+8+2x-1)\\=(5x+7)(3x+7)\)
10. \((3q+6)(q-3)+(3q+6)(4q+3)\\=(3q+6)(q-3+4q+3)\\=(3q+6)(5q+0)\)
11. \((s+2)(s-8)+(3s+4)(s+2)\\=(s+2)(s-8+3s+4)\\=(s+2)(4s-4)\)
12. \((x-7)(x-3)-(5x-5)(x-7)\\=(x-7)(x-3-5x+5)\\=(x-7)(-4x+2)\)
