Verbetersleutel

1. \((6s-1)(s-6)-(6s-1)(5s+6)\\=(6s-1)(s-6-5s-6)\\=(6s-1)(-4s-12)\)
2. \((8a+9)(a-4)+(8a+9)(5a-4)\\=(8a+9)(a-4+5a-4)\\=(8a+9)(6a-8)\)
3. \((9y-4)^2+(36y-16)\\=(9y-4)(9y-4)+4(9y-4)\\=(9y+0)(9y-4)\)
4. \((7a+3)(a+8)+(7a+3)(3a-5)\\=(7a+3)(a+8+3a-5)\\=(7a+3)(4a+3)\)
5. \((6p-1)(p+8)+(6p-1)(5p-9)\\=(6p-1)(p+8+5p-9)\\=(6p-1)(6p-1)\)
6. \((3a-1)(a+9)-(3a-1)(2a-4)\\=(3a-1)(a+9-2a+4)\\=(3a-1)(-a+13)\)
7. \((4x-3)(x-3)-(4x-3)(5x-4)\\=(4x-3)(x-3-5x+4)\\=(4x-3)(-4x+1)\)
8. \((5p-2)(p+8)-(5p-2)(3p-5)\\=(5p-2)(p+8-3p+5)\\=(5p-2)(-2p+13)\)
9. \((8q+5)^2-(32q+20)\\=(8q+5)(8q+5)-4(8q+5)\\=(8q+1)(8q+5)\)
10. \((5y-2)^2+(10y-4)\\=(5y-2)(5y-2)+2(5y-2)\\=(5y+0)(5y-2)\)
11. \((4p+1)^2-(8p+2)\\=(4p+1)(4p+1)-2(4p+1)\\=(4p-1)(4p+1)\)
12. \((p+7)(p-2)+(3p+4)(p+7)\\=(p+7)(p-2+3p+4)\\=(p+7)(4p+2)\)
