Verbetersleutel

1. \((4b-2)(b+2)+(4b-2)(3b-2)\\=(4b-2)(b+2+3b-2)\\=(4b-2)(4b+0)\)
2. \((2x+1)^2-(10x+5)\\=(2x+1)(2x+1)-5(2x+1)\\=(2x-4)(2x+1)\)
3. \((6s+7)^2-(24s+28)\\=(6s+7)(6s+7)-4(6s+7)\\=(6s+3)(6s+7)\)
4. \((7x+8)^2-(14x+16)\\=(7x+8)(7x+8)-2(7x+8)\\=(7x+6)(7x+8)\)
5. \((4x-6)(x-6)-(4x-6)(3x-2)\\=(4x-6)(x-6-3x+2)\\=(4x-6)(-2x-4)\)
6. \((7p+2)(p-4)-(7p+2)(5p-2)\\=(7p+2)(p-4-5p+2)\\=(7p+2)(-4p-2)\)
7. \((3p-9)(p+8)+(3p-9)(5p+9)\\=(3p-9)(p+8+5p+9)\\=(3p-9)(6p+17)\)
8. \((4x+1)^2+(16x+4)\\=(4x+1)(4x+1)+4(4x+1)\\=(4x+5)(4x+1)\)
9. \((s+3)(s+9)-(3s-2)(s+3)\\=(s+3)(s+9-3s+2)\\=(s+3)(-2s+11)\)
10. \((3b+2)(b+6)+(3b+2)(2b-9)\\=(3b+2)(b+6+2b-9)\\=(3b+2)(3b-3)\)
11. \((x+9)(x-2)-(5x+4)(x+9)\\=(x+9)(x-2-5x-4)\\=(x+9)(-4x-6)\)
12. \((7p+5)(p-1)+(7p+5)(2p+9)\\=(7p+5)(p-1+2p+9)\\=(7p+5)(3p+8)\)
