因式分解a²b²-a²-b²+1因式分解a²b²-a²-b²+1因式分解a²b²-a²-b
因式分解a²b²-a²-b²+1
因式分解a²b²-a²-b²+1
因式分解a²b²-a²-b²+1
a²b²-a²-b²+1
=a^2(b^2-1)-(b^2-1)
=(b^2-1)(a^2-1)
=(b+1)(b-1)(a+1)(a-1)
=(a+1)(a-1)(b+1)(b-1)
原式= a²(b²-1)-(b²-1)
=(b²-1)(a²-1)
=(b+1)(b-1)(a+1)(a-1)
原式=a²(b²-1)-(b²-1)
=(a²-1)(b²-1)
=(a+1)(a-1)(b+1)(b-1)
祝您愉快
=a²(b²-1)-(b²-1)
=(a²-1)(b²-1)
=(a+1)(a-1)(b+1)(b-1)
= a²(b²-1)-(b²-1)=(b²-1)(a²-1)=(b+1)(b-1)(a+1)(a-1)
