Verbetersleutel

1. \((8y-5)(y-8)-(8y-5)(3y-2)\\=(8y-5)(y-8-3y+2)\\=(8y-5)(-2y-6)\)
2. \((a+9)(a-3)-(5a-2)(a+9)\\=(a+9)(a-3-5a+2)\\=(a+9)(-4a-1)\)
3. \((5p-4)(p+7)+(5p-4)(2p-1)\\=(5p-4)(p+7+2p-1)\\=(5p-4)(3p+6)\)
4. \((6q+1)^2+(12q+2)\\=(6q+1)(6q+1)+2(6q+1)\\=(6q+3)(6q+1)\)
5. \((b+5)(b+1)-(2b+2)(b+5)\\=(b+5)(b+1-2b-2)\\=(b+5)(-b-1)\)
6. \((y-2)(y-5)+(2y-9)(y-2)\\=(y-2)(y-5+2y-9)\\=(y-2)(3y-14)\)
7. \((a-4)(a+8)+(5a-9)(a-4)\\=(a-4)(a+8+5a-9)\\=(a-4)(6a-1)\)
8. \((4a+1)(a-7)+(4a+1)(3a+4)\\=(4a+1)(a-7+3a+4)\\=(4a+1)(4a-3)\)
9. \((b-2)(b+9)+(4b+4)(b-2)\\=(b-2)(b+9+4b+4)\\=(b-2)(5b+13)\)
10. \((7q-8)(q-5)+(7q-8)(5q-9)\\=(7q-8)(q-5+5q-9)\\=(7q-8)(6q-14)\)
11. \((7x+6)^2-(28x+24)\\=(7x+6)(7x+6)-4(7x+6)\\=(7x+2)(7x+6)\)
12. \((s-4)(s+2)+(2s+5)(s-4)\\=(s-4)(s+2+2s+5)\\=(s-4)(3s+7)\)
