Question

计算：【6(x+2)²-8(x+2)(x-2)+10(x+2)】÷2(x+2)，结果是否等于19-x？

Answer 1

【6(x+2)²-8(x+2)(x-2)+10(x+2)】÷2(x+2)
=6(x+2)²÷2(x+2)-8(x+2)(x-2)÷2(x+2)+10(x+2)÷2(x+2)
=3(x+2)-4(x-2)+5
=3x+6-4x+8+5
=19-x
结果正确
要采纳哦，O(∩_∩)O！

Answer 2

【6(x+2)2-8(x+2)(x-2)+10(x+2)】÷2(x+2)
=6(x+2)2÷2(x+2)-8(x+2)(x-2)÷2(x+2)+10(x+2)÷2(x+2)
=3(x+2)-4(x-2)+5
=3x+6-4x+8+5
=19-x

Answer 3

【6(x+2)²-8(x+2)(x-2)+10(x+2)】÷2(x+2)
=3(x+2)-4(x-2)+5
=3x+6-4x+8+5
=19-x

Answer 4

结果正确

Answer 5

【6(x+2)²-8(x+2)(x-2)+10(x+2)】÷2(x+2)
=6(x+2)²÷2(x+2)-8(x+2)(x-2)÷2(x+2)+10(x+2)÷2(x+2)
=3(x+2)-4(x-2)+5
=3x+6-4x+8+5
=19-x
