✔ 最佳答案
ax+a+x+1
= a(x+1) + 1(x+1)
= (a+1) (x+1)

p^3+p-p^2-1
=2p^3-p^2-1
=2p^1-1
=2p-1

希望可以幫到你=]

ax+a+x+1
= a(x+1) + 1(x+1)
= (a+1) (x+1)

p^3+p-p^2-1
=2p^3-p^2-1
=2p^1-1
=2p-1

ax+a+x+1
=a(x+1)+(x+1)
=(x+1)(a+1)


p^3 + p- p^2 - 1
=p^3-p^2+p-1
=P^2(p-1)+(p-1)
=(p-1)(p^2+1)

第二題很明顯是錯誤的, 而且結果也很明顯不是題目要求的因式分解的形式!!

我是指"最佳解答" 的第二題
