Verbetersleutel

1. \((5p+6)^2+(20p+24)\\=(5p+6)(5p+6)+4(5p+6)\\=(5p+10)(5p+6)\)
2. \((7b+1)(b+6)-(7b+1)(5b-7)\\=(7b+1)(b+6-5b+7)\\=(7b+1)(-4b+13)\)
3. \((a-4)(a+8)+(3a-7)(a-4)\\=(a-4)(a+8+3a-7)\\=(a-4)(4a+1)\)
4. \((x-3)(x-6)-(3x+3)(x-3)\\=(x-3)(x-6-3x-3)\\=(x-3)(-2x-9)\)
5. \((7p+6)(p+7)+(7p+6)(3p-9)\\=(7p+6)(p+7+3p-9)\\=(7p+6)(4p-2)\)
6. \((p-9)(p-9)+(3p+7)(p-9)\\=(p-9)(p-9+3p+7)\\=(p-9)(4p-2)\)
7. \((2s-6)(s-2)+(2s-6)(3s+5)\\=(2s-6)(s-2+3s+5)\\=(2s-6)(4s+3)\)
8. \((a-8)^2-(4a-32)\\=(a-8)(a-8)-4(a-8)\\=(a-12)(a-8)\)
9. \((8s-5)^2-(24s-15)\\=(8s-5)(8s-5)-3(8s-5)\\=(8s-8)(8s-5)\)
10. \((6a+5)^2+(24a+20)\\=(6a+5)(6a+5)+4(6a+5)\\=(6a+9)(6a+5)\)
11. \((8s+1)^2+(16s+2)\\=(8s+1)(8s+1)+2(8s+1)\\=(8s+3)(8s+1)\)
12. \((a-5)(a+3)-(3a-7)(a-5)\\=(a-5)(a+3-3a+7)\\=(a-5)(-2a+10)\)
