Verbetersleutel

1. \((6p+5)^2-(30p+25)\\=(6p+5)(6p+5)-5(6p+5)\\=(6p+0)(6p+5)\)
2. \((y-9)(y+3)+(2y-6)(y-9)\\=(y-9)(y+3+2y-6)\\=(y-9)(3y-3)\)
3. \((7b+6)(b+9)-(7b+6)(5b-7)\\=(7b+6)(b+9-5b+7)\\=(7b+6)(-4b+16)\)
4. \((7p+6)(p-2)+(7p+6)(4p-6)\\=(7p+6)(p-2+4p-6)\\=(7p+6)(5p-8)\)
5. \((y+9)^2+(3y+27)\\=(y+9)(y+9)+3(y+9)\\=(y+12)(y+9)\)
6. \((6a-3)(a-7)+(6a-3)(5a-2)\\=(6a-3)(a-7+5a-2)\\=(6a-3)(6a-9)\)
7. \((p-6)(p-5)-(4p-6)(p-6)\\=(p-6)(p-5-4p+6)\\=(p-6)(-3p+1)\)
8. \((s+9)(s+2)-(3s+3)(s+9)\\=(s+9)(s+2-3s-3)\\=(s+9)(-2s-1)\)
9. \((4x-9)(x-3)-(4x-9)(5x+6)\\=(4x-9)(x-3-5x-6)\\=(4x-9)(-4x-9)\)
10. \((s-1)(s-7)+(5s+8)(s-1)\\=(s-1)(s-7+5s+8)\\=(s-1)(6s+1)\)
11. \((s-2)(s-4)+(2s+7)(s-2)\\=(s-2)(s-4+2s+7)\\=(s-2)(3s+3)\)
12. \((8q+1)^2+(32q+4)\\=(8q+1)(8q+1)+4(8q+1)\\=(8q+5)(8q+1)\)
