真懒 (x+2)(x-6)=0,第二·三题(3x+1)和(3x-1)应有平方才能做,第三题移项(2x+3)-(x-2)=0,(2x+3-x+2)(2x+3+x-2)=0,(x+5)(3x+1)=0;第五题移项3(x-5)-2(5-x)=0;3(x-5)+2(x -5)=0;5(x-5)=0.
(x+2)(x-3)(x-6)(x-1)=0
已知1+x+x^2+x^3=0,求x+x^2+x^3+x^4+x^+x^6+x^7+x^8的值
如果1+x+x^2+x^3=0,求x+x^2+X^3+x^4+x^5+x^6+x^7+x^8的值,
1/(x*x-2x-3)+2/(x*-x-6)+3/(x*x+3x+2)=0
