m^2+11n-mn-11m9-a^2-b^2-2ab1/2x^2+2xy+2y^2
m^2+11n-mn-11m
9-a^2-b^2-2ab
1/2x^2+2xy+2y^2
m^2+11n-mn-11m9-a^2-b^2-2ab1/2x^2+2xy+2y^2
m² + 11n - mn - 11m
= (m² - mn) - (11m - 11n)
= m(m - n) - 11(m - n)
= (m - n)(m - 11)
9 - a² - b² - 2ab
= 9 - (a² + b² + 2ab)
= 9 - (a + b)²
= (3 + a + b)(3 - a - b)
1/2x² + 2xy + 2y²
= 1/2 (x² + 4xy + 4y²)
= 1/2 (x + 2y)²
m^2+11n-mn-11m=m(m-n)+11(n-m)=(m-11)(m-n)
9-a^2-b^2-2ab=9-(a+b)^2=(3-a-b)(3+a+b)
1/2x^2+2xy+2y^2=(x^2+4xy+4y^2)/2=(x+2y)^2 /2
1.M(M-N)+11(M-N)=(M-N)(-11+M)
2.9-(A+B)^2=(3-A-B)(3+A+B)
3.(1/2X+Y)(X+2Y)
m^2+11n-mn-11m9-a^2-b^2-2ab1/2x^2+2xy+2y^2
mn=-2,m+n=3,则mn+11m+26n=?
(a^m)^n*(-a^3m)2n/(a^mn)^5-a^2mn
若(m+n)^2-mn(m+n)=(m+n)·M,则M是() A.m^2+n^2 B.m^2-mn+n^2 C.m^2-3mn+n^2 D.m^2+mn+n^2
3m^2+11mn+6n^2
已知m*m+n*n=a*a,求m*m-2mn的最小值
m^2-mn=16 m^2-n=11 求2mn+2n的值
m^2-mn=16 m^2-n=11 求2mn+2n的值
已知m+n=11,mn=30,则m^2+n^2= 若-3
已知(m+n)^2=11,mn=1,求(m-n)^2的值
已知|2m-4|+根号3n+3=0,求7m-11n+mn
化简:n-mn-3(-mn-n)-(-m)-11
a^2-m^2+2mn-n^2因式分解
【数学】(a^m)^n(-a^3m)^2n/(a^mn)^5=?
2mn[(2mn)^2-3n(mn+m^2*n)-mn^2]计算
2mn[(2mn)²-3n(mn+m²n)-mn²
(5mn-2m+3n)+(-7m-7mn)
