Verbetersleutel

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