25x(0.4-y)-10y(y-0.4)分解因式
25x(0.4-y)-10y(y-0.4)分解因式
25x(0.4-y)-10y(y-0.4)分解因式
25x(0.4-y)-10y(y-0.4) =5(0.4-一Y)^2(5X-2Y) =5(0.4-Y)(0,4-Y)(5X-2Y)
25x(0.4-y)-10y(y-0.4)分解因式
(x+y)²-10(x+y)+25
25(x-y)*2+10(y-x)+125(x-y)^2+10(y-x)+1
(x+y)(x+y-10)+25=0,且x-y=3,求x,y
(x+y)(x+y-10)+25=0,且x-y=3,求x,y
25X(0.4-Y)²+10Y(Y-0.4)²,其中X=0.04 Y=2.4 先分解因式在求值
先分解因式,再求值 25x(0.4-y)2-10y(y-0.4)2,其中x=0.04,y=2.4
25x(0.4-y)的平方-10y(y-0.4)的平方,其中x=0.04,y=2.4 先分解因式,再求值
先因式分解,在求值:25x乘((0.4-y)^2)-10y乘(y-0.4)^2,其中x=0.04,y=2.4.
{(x,y) |x|+|y|
x>y?x:y
(x-y)^2+10(y-x)+25因式分解 (x-y)²-10(y-x)+25(x-y)²+10(y-x)+25只要结果
设Var(X)=25,Var(y)=36,pXY=0.4,求Var(X+Y)和Var(X-Y).
方程式 y=x+6 x=y*0.4 求解
0.3x+0.4y+0.5(10-x-y)=3.8解出2x+y=12详细解法
(y-x)²-10x+10y+25因式分解,
X*Y,当Y
y满足x-y+2≥0,x+y-4≥0,2x-y-5≤0 求X^2+Y^2-10Y+25的最小值
