解答
(2a^2+3ab^2)+(3a^2+3ab)
=2a^2+3ab^2+3a^2+3ab
=(2+3)a^2+3ab^2+3ab
=5a^2+3ab^2+3ab
推荐
- 给出三个多项式2a^2+3ab+b^2+3ab
- 现有三个多项式:1/2a²+a-4,1/2a²+5a+4,1/2a²-a,请你选择中两个进行加法或减法的运算.
- 给出三个多项式X=2a2+3ab+b2，Y=3a2+3ab，Z=a2+ab，请你任选两个进行加（或减）法运算，再将结果分解因式．
- 已知三个多项式A=ab+3b^2,B=2A^2+3ab-b^2,C=a^2-3ab-2b^2,任选2个进行加法运算,结果分解因式
- 给出三个多项式2a^2+3ab+b^2,3a^+3ab,a^+ab请你任选两个进行加(或减)法运算,再将结果分解因式
