Verbetersleutel

1. \((7p-4)(p-6)+(7p-4)(3p+9)\\=(7p-4)(p-6+3p+9)\\=(7p-4)(4p+3)\)
2. \((y-5)(y+2)-(2y-6)(y-5)\\=(y-5)(y+2-2y+6)\\=(y-5)(-y+8)\)
3. \((s-1)(s+3)+(4s+1)(s-1)\\=(s-1)(s+3+4s+1)\\=(s-1)(5s+4)\)
4. \((6s+1)^2+(12s+2)\\=(6s+1)(6s+1)+2(6s+1)\\=(6s+3)(6s+1)\)
5. \((3p-3)(p+7)+(3p-3)(5p-6)\\=(3p-3)(p+7+5p-6)\\=(3p-3)(6p+1)\)
6. \((4x-3)^2+(16x-12)\\=(4x-3)(4x-3)+4(4x-3)\\=(4x+1)(4x-3)\)
7. \((p-6)(p-4)-(2p+7)(p-6)\\=(p-6)(p-4-2p-7)\\=(p-6)(-p-11)\)
8. \((q+4)(q-5)+(5q+1)(q+4)\\=(q+4)(q-5+5q+1)\\=(q+4)(6q-4)\)
9. \((q-8)(q-9)+(2q+2)(q-8)\\=(q-8)(q-9+2q+2)\\=(q-8)(3q-7)\)
10. \((a+4)(a+3)+(5a+5)(a+4)\\=(a+4)(a+3+5a+5)\\=(a+4)(6a+8)\)
11. \((3p-3)(p-9)+(3p-3)(2p-8)\\=(3p-3)(p-9+2p-8)\\=(3p-3)(3p-17)\)
12. \((x-3)(x+4)-(2x-8)(x-3)\\=(x-3)(x+4-2x+8)\\=(x-3)(-x+12)\)
