3m^2+11mn+6n^2
3m^2+11mn+6n^2
3m^2+11mn+6n^2
分解因式?
3m²+11mn+6n²
3m 2n
m 3n
=(3m+2n)(m+3n)
m-n=7 mn=-5求(3m+5n+4mn)-(2n-4n+6mn)
已知MN^2=-6,求-MN(M^2N^5-MN^3-N)的值
3m^2+11mn+6n^2
mn=-2,m+n=3,则mn+11m+26n=?
2mn[(2mn)^2-3n(mn+m^2*n)-mn^2]计算
2mn[(2mn)²-3n(mn+m²n)-mn²
(5mn-2m+3n)+(-7m-7mn)
(5mn-2m+3n)+(-7m-7mn)
已知m²-mn=15,mn-n²=-6,求代数式3m²-mn-2n²
先化简,再求值(3M-5M+4MN)-(2M-4N+6MN)
已知n^2-mn=15,mn-n^2=-6,求3*m^2-mn-n^2的值
急2[mn+(-3m)]-3(2n-mn),m+n=2 mn=-3
3(m^2n+mn)-4(mn-2m^2n)+mn.要有过程
计算:[-m^3n/(m-n)^2]^4*[(n^2-mn)/m]^3/m^4n^10*[(mn-n^2)/m]^6
1/M+1/N=5 (3M+MN+2N) / (M-MN=3N)
已知m-n=2,mn=1,求多项式(-2mn+2mn+3n)-(3mn+2n-2m)-(m+4n+mn)的值
已知m-n=2,mn=1,求多项式(-2mn+2mn+3n)-(3mn+2n-2m)-(m+4n+mn)的值
已知m+n=3,mn=2/3,求mn-mn+mn的值
