Verbetersleutel

1. \((7b+6)(b-5)-(7b+6)(4b-3)\\=(7b+6)(b-5-4b+3)\\=(7b+6)(-3b-2)\)
2. \((y+5)(y+9)+(4y-1)(y+5)\\=(y+5)(y+9+4y-1)\\=(y+5)(5y+8)\)
3. \((6y-8)(y-8)+(6y-8)(5y+1)\\=(6y-8)(y-8+5y+1)\\=(6y-8)(6y-7)\)
4. \((5x-7)(x+7)+(5x-7)(4x+3)\\=(5x-7)(x+7+4x+3)\\=(5x-7)(5x+10)\)
5. \((2p-1)(p-4)+(2p-1)(5p-9)\\=(2p-1)(p-4+5p-9)\\=(2p-1)(6p-13)\)
6. \((x-8)^2+(3x-24)\\=(x-8)(x-8)+3(x-8)\\=(x-5)(x-8)\)
7. \((8p+7)(p+4)+(8p+7)(3p-3)\\=(8p+7)(p+4+3p-3)\\=(8p+7)(4p+1)\)
8. \((x+5)(x-5)-(5x-5)(x+5)\\=(x+5)(x-5-5x+5)\\=(x+5)(-4x+0)\)
9. \((3s-1)(s-2)+(3s-1)(4s-7)\\=(3s-1)(s-2+4s-7)\\=(3s-1)(5s-9)\)
10. \((a-4)(a+1)-(5a-8)(a-4)\\=(a-4)(a+1-5a+8)\\=(a-4)(-4a+9)\)
11. \((q+1)(q-5)+(4q-3)(q+1)\\=(q+1)(q-5+4q-3)\\=(q+1)(5q-8)\)
12. \((7a-8)(a+1)+(7a-8)(4a-7)\\=(7a-8)(a+1+4a-7)\\=(7a-8)(5a-6)\)
