(a2+2ab-4)(a2+2ab-2)+1 因式分解
(a2+2ab-4)(a2+2ab-2)+1 因式分解
(a2+2ab-4)(a2+2ab-2)+1 因式分解
(a2+2ab-4)(a2+2ab-2)+1
=（a^2 +2ab）^2 - 6(a^2 +2ab) +8+1
=（a^2 +2ab）^2 - 6(a^2 +2ab) +9
= (a^2 +2ab -3)^2

请及时选为满意答案,
(a²+2ab-4)(a²+2ab-2)+1
=[(a²+2ab)-4][(a²+2ab)-2]+1
=(a²+2ab)²-6(a²+2ab)+8+1
=(a²+2ab)²-6(a²+2ab)+9
=[(a²+2ab)-3]²
=(a²+2ab-3)²
明白请采纳，有疑问请追问！

(a²+2ab-4)(a²+2ab-2)+1
令a²+2ab=t
=(t-4)(t-2)+1
=t²-6t+9
=(t-3)²
=(a²+2ab-3)²
(a2+2ab-4)(a2+2ab-2)+1
=(a^2+2ab)^2-6(a^2+2ab)+8+1
=(a^2+2ab)^2-6(a^2+2ab)+9
=(a^2+2ab-3)^2
(a2+2ab-4)(a2+2ab-2)+1 因式分解
a2-2ab+b2
(3a2-3ab+2b2)+(a2+4ab-2b2)=4a2+ab+b2
(a2+2ab+b2)-(a2-2ab+b2)化简
化简 3a2-ab/3a2+5ab-2b2
如果a2+ab=4,ab+b2=-1,那么a2-b2=?,a2+3ab+2b2=?
a2-4ab+2b2怎么因式分解
2a2-8ab+4b2 因式分解
a2b+ab2分之a2+2ab+b2-(a2-ab2分之a2-2ab+b2)
已知a2-2ab=3,b2-ab=4,那么2b2-a2的值
如果a2-5ab+4b2=0,则 a2+2b2 3ab =
(a2-b2)/(a2+2ab+b2)*(a3+b3)
已知a2-ab=3,3ab-b2=4,则多项式2(a2+ab-b2)+a2-2ab+b2的值是2是平方的意思
3(a2-2ab)-(-ab+b2)+(2ab+b2)
计算：a2-2ab/-ab+b2÷(a2/a-b÷2ab/2b-a)
若a2+ab=5,ab+b2=4,则a2+2ab+b2的值是?
如果a2 +ab=4 ab+b2=－2 求a2+3ab+b2的值
已知：a2-ab=3,ab-2b2=-1,求a2-3ab+4b2的值
