Verbetersleutel

1. \((6s+1)^2+(24s+4)\\=(6s+1)(6s+1)+4(6s+1)\\=(6s+5)(6s+1)\)
2. \((3a+3)(a-7)-(3a+3)(2a-8)\\=(3a+3)(a-7-2a+8)\\=(3a+3)(-a+1)\)
3. \((6x+7)^2-(30x+35)\\=(6x+7)(6x+7)-5(6x+7)\\=(6x+2)(6x+7)\)
4. \((s+7)(s+6)-(2s+3)(s+7)\\=(s+7)(s+6-2s-3)\\=(s+7)(-s+3)\)
5. \((3a-4)(a+2)-(3a-4)(4a-7)\\=(3a-4)(a+2-4a+7)\\=(3a-4)(-3a+9)\)
6. \((3b-2)^2-(12b-8)\\=(3b-2)(3b-2)-4(3b-2)\\=(3b-6)(3b-2)\)
7. \((9x+7)^2+(18x+14)\\=(9x+7)(9x+7)+2(9x+7)\\=(9x+9)(9x+7)\)
8. \((3p+7)(p-4)+(3p+7)(4p-9)\\=(3p+7)(p-4+4p-9)\\=(3p+7)(5p-13)\)
9. \((4p-4)(p+5)+(4p-4)(3p-2)\\=(4p-4)(p+5+3p-2)\\=(4p-4)(4p+3)\)
10. \((7b-8)(b-4)-(7b-8)(3b+6)\\=(7b-8)(b-4-3b-6)\\=(7b-8)(-2b-10)\)
11. \((7b-3)^2-(14b-6)\\=(7b-3)(7b-3)-2(7b-3)\\=(7b-5)(7b-3)\)
12. \((p-4)(p+3)+(5p-4)(p-4)\\=(p-4)(p+3+5p-4)\\=(p-4)(6p-1)\)
