Verbetersleutel

1. \((7s+6)(s+6)+(7s+6)(3s-2)\\=(7s+6)(s+6+3s-2)\\=(7s+6)(4s+4)\)
2. \((x+1)(x-3)+(3x+7)(x+1)\\=(x+1)(x-3+3x+7)\\=(x+1)(4x+4)\)
3. \((4b+1)^2+(20b+5)\\=(4b+1)(4b+1)+5(4b+1)\\=(4b+6)(4b+1)\)
4. \((5s+3)(s+4)+(5s+3)(4s-6)\\=(5s+3)(s+4+4s-6)\\=(5s+3)(5s-2)\)
5. \((a+8)(a+1)-(4a-2)(a+8)\\=(a+8)(a+1-4a+2)\\=(a+8)(-3a+3)\)
6. \((2y-8)(y+2)-(2y-8)(5y+6)\\=(2y-8)(y+2-5y-6)\\=(2y-8)(-4y-4)\)
7. \((4q-6)(q+4)+(4q-6)(3q-3)\\=(4q-6)(q+4+3q-3)\\=(4q-6)(4q+1)\)
8. \((y+1)^2+(3y+3)\\=(y+1)(y+1)+3(y+1)\\=(y+4)(y+1)\)
9. \((x-3)(x-8)+(5x+3)(x-3)\\=(x-3)(x-8+5x+3)\\=(x-3)(6x-5)\)
10. \((5q-1)(q-8)-(5q-1)(4q+1)\\=(5q-1)(q-8-4q-1)\\=(5q-1)(-3q-9)\)
11. \((8q+1)^2-(32q+4)\\=(8q+1)(8q+1)-4(8q+1)\\=(8q-3)(8q+1)\)
12. \((7y-3)^2+(21y-9)\\=(7y-3)(7y-3)+3(7y-3)\\=(7y+0)(7y-3)\)
