(-3a^2-9a^3b+12a^4b^2)/(-3a^2)= 16(2m-n)^p加2/【-4(2m-n)^p-1】=
(-3a^2-9a^3b+12a^4b^2)/(-3a^2)= 16(2m-n)^p加2/【-4(2m-n)^p-1】=
(-3a^2-9a^3b+12a^4b^2)/(-3a^2)= 16(2m-n)^p加2/【-4(2m-n)^p-1】=
(-3a^2-9a^3b+12a^4b^2)/(-3a^2)
=1+3ab-4a²b²
16(2m-n)^p加2/【-4(2m-n)^p-1】
=-4(2m-n)^(p+2-p+1)
=-4(2m-n)³
2(a+b)-[4(a+b)-3(a+b)]一[5(a-b)+(a-b)]过程
1/4(a-b)^2+3(a-b)(a+b)+9(a+b)^2
(a^2+1)(-4a^2+1)+a^4-1 3a(a-b)(a+b)-6(b-a)^2a^2-9(a-b)^2= 3a(a-b)(a+b)-6(b-a)^2=
5(a*a*b-3*a*a*b)-2*(a*a*b-7*a*b*b)
(a+2b)(a-2b)+(a-b)(a+b)-2(a-3b)(a-b)
9(a-b)(a+b)-3(a-b)^2
2a(a-b)+4a(2a+3b)
等式:(a+b)^0=1 (a+b)^1=a+b (a+b)^2(a+b)^0=1(a+b)^1=a+b(a+b)^2=a^2+2ab+b^2(a+b)^3=a^3+3a^2b+3ab^2+b^3问:(a+b)^4=?(a+b)^5=?``````` (a+b)^9=?
(a-2b)(a^2+2ab+4b^2)-a(a+3b)(a-3b),其中a=-1/9,b=1求a,b
a=3b-5,求4(3b-a)^2-36b+12a+9
计算:(4a-b)^2-[8a*(a-b)-(3a-b)*(3a+b)]
(2/3a)-[2/(a+b)]{[(a+b)/3a]-a-b}÷[(a-b)/b]
(2/3a)-[2/(a+b)]{[(a+b)/3a]-a-b}÷[(a-b)/a]
化简:[2/3a - 2/(a+b) * (a+b/3a - a - b)] / (a-b)/a
2b根号a/b+3/a根号a立方b-(4a根号b/a+根号9ab)
(2a-3b)[(a+b)-b(a-3b)]
3a^2b-{2a^2b+[9a^b-(6a^2b+4a^2)]-(3a^2b-8a^2)}=
a+2b/2a-3b=3 求解4b+2a/9b-6a-4a-6b/3a+6b=?
