解答
2(x^2-3y^2)62+24x^2y^2 = 2(x^4+9y^4-6x^2y^2)+24x^2y^2 = 2x^4+18y^4-12x^2y^2+24x^2y^2
=2x^4+18y^4+12x^2y^2 = 2(x^4+6x^2y^2+9y^4) = 2(x^2+3y^2)^2
推荐
- x^3y^3*(x^2y^2)^-3
- 因式分解:2(x^3-3y^2)^2+24x^2y^2
- (24x^2y^2-(2x^2+3y)(2x^2-3y)-9y^2)/x^3y^2
- 已知x-2y/3y-x=2/3,则y/x的值是
- 2x^2y^3+x^2y^2/5x^3y^2-x^2y^2=?
- 用now,new,in,house,live,they,a.造句
- 已知三角形ABC的内切圆圆O分别和BC,AC,AB切与点D,E,F,如果AF等于2,BD等于7,CE等于4
- 计算下面圆柱体的表面积.(1)底面积直径是0.6m,高45cm.(2)底面周长是2826cm,高30cm.
