分解因式:(a-b)(3a+b)²+(a+3b)²(b-a)
分解因式:(a-b)(3a+b)²+(a+3b)²(b-a)
分解因式:(a-b)(3a+b)²+(a+3b)²(b-a)
(a-b)(3a+b)²+(a+3b)²(b-a)
=(a-b)(3a+b)²-(a+3b)²(a-b)
=(a-b)[(3a+b)²-(a+3b)²]
=(a-b)[(3a+b)+(a+3b)][(3a+b)-(a+3b)]
=(a-b)(4a+4b)(2a-2b)
=8(a+b)(a-b)²
=(b-a)((a+3b)^2-(3a+b)^2)
=(b-a)(4a+4b)(2b-2a)
=8(b-a)^2(a+b)
(a-b)(3a+b)²+(a+3b)²(b-a)
=(a-b)(3a+b)²-(a+3b)²(a-b)
=(a-b)[(3a+b)²-(a+3b)²]
=(a-b)(3a+b+a+3b)(3a+b-a-3b)
=8(a-b)(a+b)(a-b)
=8(a-b)^2(a+b)
=(a-b)〔(3a+b)^2-(a+3b)^2〕
=(a-b)(3a+b+a+3b)〔(3a+b)-(a+3b)〕
=8(a-b)^2(a+b)
(a-b)(3a+b)²+(a+3b)²(b-a)
=(a-b)((3a+b)²-(a+3b)²)
=(a-b)(9a²+6ab+b²-a²-6ab-9b²)
=(a-b)(8a²-8b²)
=8(a-b)(a-b)(a+b)
=8(a-b)²(a+b)
(a-b)(9a²+6ab+b²-a²-6ab-9b²)=(a-b)8(a²-b²)=8(a-b)(a-b)(a+b)=(a-b)²(a+b)
(a-b)(3a+b)²+(a+3b)²(b-a)
=(a-b)(3a+b)-(a-b)(a+3b)
=(a-b)[(3a+b)²-(a+3b)²]
=(a-b)(3a+b-a-3b)(3a+b+a+3b)
=8(a-b)²(a+b)
