Verbetersleutel

1. \((8b+4)(b+2)+(8b+4)(5b-3)\\=(8b+4)(b+2+5b-3)\\=(8b+4)(6b-1)\)
2. \((b+6)(b-7)+(2b-3)(b+6)\\=(b+6)(b-7+2b-3)\\=(b+6)(3b-10)\)
3. \((6x+5)(x-1)+(6x+5)(5x-8)\\=(6x+5)(x-1+5x-8)\\=(6x+5)(6x-9)\)
4. \((8p+1)^2-(40p+5)\\=(8p+1)(8p+1)-5(8p+1)\\=(8p-4)(8p+1)\)
5. \((4y+7)^2-(16y+28)\\=(4y+7)(4y+7)-4(4y+7)\\=(4y+3)(4y+7)\)
6. \((6y+5)^2-(18y+15)\\=(6y+5)(6y+5)-3(6y+5)\\=(6y+2)(6y+5)\)
7. \((q+1)(q-7)+(5q+6)(q+1)\\=(q+1)(q-7+5q+6)\\=(q+1)(6q-1)\)
8. \((x+5)(x-3)+(5x-3)(x+5)\\=(x+5)(x-3+5x-3)\\=(x+5)(6x-6)\)
9. \((5x+6)(x-4)-(5x+6)(2x-9)\\=(5x+6)(x-4-2x+9)\\=(5x+6)(-x+5)\)
10. \((3s-2)(s+3)-(3s-2)(2s-9)\\=(3s-2)(s+3-2s+9)\\=(3s-2)(-s+12)\)
11. \((x+7)(x-1)-(2x+9)(x+7)\\=(x+7)(x-1-2x-9)\\=(x+7)(-x-10)\)
12. \((5p-7)(p-9)-(5p-7)(4p-7)\\=(5p-7)(p-9-4p+7)\\=(5p-7)(-3p-2)\)
