数学题[6(x+2)ˇ2-8(x+2)(x-2)+(x+2)]/2(x+2)是初一数学题 8.4整式除法
数学题[6(x+2)ˇ2-8(x+2)(x-2)+(x+2)]/2(x+2)
是初一数学题 8.4整式除法

数学题[6(x+2)ˇ2-8(x+2)(x-2)+(x+2)]/2(x+2)是初一数学题 8.4整式除法
原式=6(x+2)ˇ2/2(x+2)-8(x+2)(x-2)/2(x+2)+(x+2)/2(x+2)
=3(x+2)-4(x-2)+0.5
=3x+6-4x+8+0.5
=14.5-x

[6(x+2)^2-8(x+2)(x-2)+(x+2)]/2(x+2)
=6(x+2)^2/2(x+2)-8(x+2)(x-2)/2(x+2)+(x+2)/2(x+2)
=3(x+2)-4(x-2)+0.5
=3x+6-4x+8+0.5
=14.5-x

原式=6(x+2)ˇ2/2(x+2)-8(x+2)(x-2)/2(x+2)+(x+2)/2(x+2)
=3(x+2)-4(x-2)+0.5
=3x+6-4x+8+0.5
