Verbetersleutel

1. \((6p+7)(p+2)+(6p+7)(5p+5)\\=(6p+7)(p+2+5p+5)\\=(6p+7)(6p+7)\)
2. \((s+3)(s-8)+(4s+8)(s+3)\\=(s+3)(s-8+4s+8)\\=(s+3)(5s+0)\)
3. \((2x+1)^2+(8x+4)\\=(2x+1)(2x+1)+4(2x+1)\\=(2x+5)(2x+1)\)
4. \((2p+5)(p+7)+(2p+5)(3p+4)\\=(2p+5)(p+7+3p+4)\\=(2p+5)(4p+11)\)
5. \((5q+2)^2-(25q+10)\\=(5q+2)(5q+2)-5(5q+2)\\=(5q-3)(5q+2)\)
6. \((s-8)^2+(4s-32)\\=(s-8)(s-8)+4(s-8)\\=(s-4)(s-8)\)
7. \((7y-1)(y+4)+(7y-1)(3y-8)\\=(7y-1)(y+4+3y-8)\\=(7y-1)(4y-4)\)
8. \((7y-7)(y+5)+(7y-7)(2y+1)\\=(7y-7)(y+5+2y+1)\\=(7y-7)(3y+6)\)
9. \((p+4)(p+4)-(2p-1)(p+4)\\=(p+4)(p+4-2p+1)\\=(p+4)(-p+5)\)
10. \((5y-4)^2+(15y-12)\\=(5y-4)(5y-4)+3(5y-4)\\=(5y-1)(5y-4)\)
11. \((x+7)(x+5)-(4x-6)(x+7)\\=(x+7)(x+5-4x+6)\\=(x+7)(-3x+11)\)
12. \((6b+4)(b-1)-(6b+4)(5b-6)\\=(6b+4)(b-1-5b+6)\\=(6b+4)(-4b+5)\)
