计算:(3x-y+4)(3x+y-4)
计算:(3x-y+4)(3x+y-4)
计算:(3x-y+4)(3x+y-4)计算:(3x-y+4)(3x+y-4)
我来帮你解答,等我哦
(3x-y+4)(3x+y-4)
=[3x-(y-4)][3x+(y-4)]
=9x²-(y-4)²
=9x²-y²+8y-16
计算 3x+4y/x-y+3y/y-x-4x/x-y
一道数学计算题,要计算过程,{12(x+y)^3(y-x)}^3÷{4(x+y)^2(x-y)}^2
计算题:(9x-4y)(-3x+2y)(-2y-3x)
初一计算题:【3(x-y)²】·【-2(x-y)】·【5/4(x-y)】
计算(2x-3y)(x+4y)-(3x+y)(x-2y)(2x-3y)(x+4y)-(3x+y)(x-2y)
