(x+y)^2-9x-9y-14(x+y)^2-9x-9y-14(x+y)^2-9x-9y-14应该是+4吧(x+y)^2-9x-9y+14=(x+y)^2-9(x+y)+14=(x+y-7)(x+y
(x+y)^2-9x-9y-14
(x+y)^2-9x-9y-14
(x+y)^2-9x-9y-14
应该是+4 吧
(x+y)^2-9x-9y+14
=(x+y)^2-9(x+y)+14
=(x+y-7)(x+y-2)
(x+y)^2-9x-9y-14
(x+y)^2-9y^2
9(x-y)-12(y-x)^2
(x+y)^2+6(x+y)+9
(x+y)^2-9(x+y)+18
计算:1.(x-1)^2+2(1-x) 2.(x-y)/(x+3y)÷(x^2-y^2)/(x^2+6xy+9y^2)-2y/(x+y)1.(x-1)^2+2(1-x)2.(x-y)/(x+3y)÷(x^2-y^2)/(x^2+6xy+9y^2)-2y/(x+y)
9(x+y)^2-16(x-y)^2
4-12(x-y)+9(x-y)^2 因式分解
4(x+y)^2-12(x+y)+9因式分解
4(x+y)^2-12(x+y)+9
4x^-9y^-(2x+3y)
(x-y)/(x+3y)*(x²+6xy+9y²)/(x²-y²)-2y/(x+y)
计算或化简:[(x-y)/(x+3y)]÷[(x²-y²)/(x²+6xy+9y²)]-(2y)/x+y
化简:(x+y)+(2x+y/1*2)+(3x+y/2*3)+...+(9x+y/8*9)
(x+2y)^2-(2x-y)^2 还有9(2x-y)^2-4(x+2y)^2
3(x+y)-2(x-y)=11 4(x+y)+3(x-y)=9
合并同类项 9(X+Y)-2(X+Y)-6(X+Y)=x+Y
因式分解 (1).(x+y)(x+y-6)+9 (2).x²-16y²-x-4y
