Verbetersleutel

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