求y=(2+3x)(3-5x+x^2)的导数
哥们们,三个人答案没一个相同的,让不让我活了
求y=(2+3x)(3-5x+x^2)的导数哥们们,三个人答案没一个相同的,让不让我活了
y=(2+3x)(3-5x+x²)
=3x³-13x²-x+6
y'=9x²-26x-1
y = (2+3x)(3-5x+x^2)
y' = (2+3x)'(3-5x+x^2) + (2+3x)(3-5x+x^2)'
y' = 3 * (3-5x+x^2) + (2+3x) * (-5 + 2x)
Y'=(2+3X)'(3-5X+X^2)+(2+3X)(3-5X+X^2)'=3(3-5X+X^2)+(2+3X)(-5+2X)=9-15X+3X^2-10-15X+4X+6X^2=9X^2-26X-1
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
y=3(x-y),x=2(x-y)求x,y的值
已知x-y=3,求[(x+y)(x-y)-(x-y)^2+2y(x-y)]除以的值
若x-y/x+y=5,求x-y/2x+2y+5x+5y/3x-3y的值
(x-y)/(x+y)=3求( 3x-2y-1)/(x+y-5)
若x+y分之x-y=3,求式子x+y分之5(x-y)—2(x-y)分之x+y的值
若x-y分之x+y=3,求式子x+y分之5(x-y)—2(x-y)分之x+y的值
2x+3y/5x-3y=3/5求x/y的值
求5x-2y=x-y=4x-3y-2的解
x+y/3x-2y=5/3 求x:y的比值
已知3x-2y/x+y=5/3求x;y的值
已知x+y/3x-2y=5/3求x;y的值
已知5|x+y-3|+(x-2y)²=5,求x+y的值
(x+y-5)+|3y-2x+10|=0,求 x,y的值
1.已知:x-2y=3,求[(3x+2y)(3x-2y)-(x+2y)(5x-2y)]除4x 的值
