Verbetersleutel

1. \((4b+9)(b-8)-(4b+9)(3b-3)\\=(4b+9)(b-8-3b+3)\\=(4b+9)(-2b-5)\)
2. \((6p+1)^2-(18p+3)\\=(6p+1)(6p+1)-3(6p+1)\\=(6p-2)(6p+1)\)
3. \((a-4)(a-9)-(2a+6)(a-4)\\=(a-4)(a-9-2a-6)\\=(a-4)(-a-15)\)
4. \((p+4)(p-2)-(5p-4)(p+4)\\=(p+4)(p-2-5p+4)\\=(p+4)(-4p+2)\)
5. \((s+2)(s-5)-(5s+7)(s+2)\\=(s+2)(s-5-5s-7)\\=(s+2)(-4s-12)\)
6. \((2p-1)(p-6)-(2p-1)(3p-6)\\=(2p-1)(p-6-3p+6)\\=(2p-1)(-2p+0)\)
7. \((7p-1)(p+4)-(7p-1)(3p-6)\\=(7p-1)(p+4-3p+6)\\=(7p-1)(-2p+10)\)
8. \((8a+5)^2+(40a+25)\\=(8a+5)(8a+5)+5(8a+5)\\=(8a+10)(8a+5)\)
9. \((8s-7)^2-(16s-14)\\=(8s-7)(8s-7)-2(8s-7)\\=(8s-9)(8s-7)\)
10. \((q-2)(q+4)+(4q-7)(q-2)\\=(q-2)(q+4+4q-7)\\=(q-2)(5q-3)\)
11. \((s-8)(s+5)-(4s+3)(s-8)\\=(s-8)(s+5-4s-3)\\=(s-8)(-3s+2)\)
12. \((s+4)(s+9)+(2s+5)(s+4)\\=(s+4)(s+9+2s+5)\\=(s+4)(3s+14)\)
