25-9q^4
=-(9q^4-25)
=-(3q²+5)(3q²-5)
16x^2-(y+z)^2
=(4x)²+(y+z)²
=(4x+y+z)(4x-y-z)
a^4-16b^4
=(a²+4b²)(a²-4b²)
=(a²+4b²)(a+2b)(a-2b)
]
9m^2+6mn^2+n^4
=(3m+n²)²
已知x、y、z∈R,且x+y+z、x+y-z、x-y+z、-x+y+z成等比数列,公比为q,则q^3+q^2+q的
已知x+2y+4z=1,q求x^+y^+z^的最小值
秋节四元一次方程式4x+2y+8z+16Q=682x-12y+12z+q=7x+13y-11z+11q=256x+11y-5z-10q=93x+4y-z+5q=632x+2y-3z+3q=283x-y+3z+3q=237x-6y-2z-q=1
25-9q^4.16x^2-(y+z)^2.a^4-16b^4.9m^2+6mn^2+n^4.因式分解解答过程
已知x:y:z=2:3:4,且x+y+z=18,求x,y,z的值quickly~Q-Q,要过程如果好还会加
3Q一定要有过程.1】 x-2y= ─9 2】3x-y+z=4 3】y=2x-7 4】4x+9x=12 y-z=3 2x+3y-z=12 5x+3y+2z=2 3y-2z=1 2z+x=47 x+y+z=6 3x-4z=4 7x+5z=4/19 4】x:y=3:2 5】x+y+z=26 6】x+y=3 7】x-y-z=2 y:z=5:4 x-y=1 y+z=5 y-z-x= ─5 x+y+z=66 2x-y+z=18
已知:x/6=y/4=z/3(x.y.z均不为零)则x+3y/3y-2z等于多少?3Q
已知p+q+r=9,且p/(x^2-yz)=q/(y^2-zx)=r/(z^2-xy) ,则(px+qy+rz)/(x+y+z)等于?为什么能列出p/(x^2-yz)=q/(y^2-zx)=r/(z^2-xy)=(px+qy+rz)/(x^3+y^3+z^3-3xyz)?过程具体点.
六年级三元一次方程组.解下列方程组:(1)5x-3y+z=25x+2y-4z=3-5x+y-z=2(2)x-y-z=-13x_5y+7z=114x-y+2z=-1(3)9x-5y+z=-69x+y+4z=3-9x+3y-5z=0(4)x+y=22x+z=-27y+z=13
讨论Z=x^2/2p+y^2/2q(p,q>0)的极值
正数x,y,z满足5x+4y+3z=10求证25x^2/(4y+3z)+16y^2/(3z+5x)+9z^2/(5x+4y)>=5
已知x,y,z为非负实数,p=-3x+y+2z,q=x-2y+4z,x+y+z=1,求p^2+q^2的最大值
为什么Y=X(1+q^n),Z=X(1+q^n+q^2n)
已知x,y,z为非负实数,p=-3x+y+2z,q=x-2y+4z,x+y+z=1,则点(p,q)的活动范围是
设x>=0,y>=0,z>=0,p=-3x+y+2z,q=x-2y+4z,x+y+z=1,求点(p,q)活动范围过程,谢谢
因式分解:25x y^2 z^2 (x+y-z)-30xyz(z-x-y)^2+5x y z^3 (z-x-y)
已知x-y/x+y=y+z/2(y-z)=z+x/3(z-x),求证8x+9y+5z=0THX..
X/10=Y/8=Z/9,则X+Y+Z/2Y-3Z
