x2+3x=6求x3+x2-12x+10的值（x后边是平方）.x2+3x=6求x3+x2-12x+10的值（x后边是平方）.x2+3x=6求x3+x2-12x+10的值（x后边是平方）.x2+3x=6

x2+3x=6求x3+x2-12x+10的值（x后边是平方）.
x2+3x=6求x3+x2-12x+10的值（x后边是平方）.

x2+3x=6求x3+x2-12x+10的值（x后边是平方）.
x2+3x=6
x^2=6-3x
x3+x2-12x+10
=x(6-3x)+x^2-12x+10
=-2x^2-6x+10
=-2(x^2+3x)+10
=-2*6+10
=-2

已知x2+3x=6,求x3+x2-12x+10的值快 x2+3x=6求x3+x2-12x+10的值（x后边是平方）. x2+3x=6求x3+x2-12x+10的值（x后边是平方）已知x2+5x-4=0,求x3+6x2+x+2的值已知x2+x-1=0,求x3+2x2+3的值已知x2+5x-4=0,求x3+6x2-4x+10的值已知x2+5x-990=0,求x3+6x2-985x+10的值 x2+3x-2=0,求2x3+6x2-4x的值已知x2-3x+1=0,求x4-6x3+4x2+15x+2 已知3x2-x=1,求代数式6x3+7x2-5x+2010 已知3x2-x=1,求6x3+7x2-5x+2000. 若3x2-x=1,求6x3+7x2-5x+2009的值若(x-2)(x2+mx+n)=x3+3x2-7x-6,求m、nrt 若 x2-3x+1=0,求（2x2×x3-5x2×x2+2 x3-8x2 ）÷（x2+1 ）的值若X1,X2,X3,X4,X5 满足方程组：2X1+X2+X3+X4+X5=6,①X1+2X2+X3+X4+X5=12 ②X1+X2+2X3+X4+X5=24 ③X1+X2+X3+2X4+X5=48 ④X1+X2+X3+X4+2X5=96 ⑤⑴求X1+X2+X3+X4+X5的值；⑵求3X3+2X4-X5有必要说明一下,凡是跟在X后面的数字都是小已知x2-3x-1=0求x3-3x2-11x+8的值已知X2-X-1=0求,X5-X4-3X3+3X2+X的值 x2+x-3=0 求x3+3x2-x+2 x2+3x-1=0,求x3+5x2+5x+2010的值
