如何解方程 (1+根号2)X^2-(1-根号2)X=0
(1+根号2)X^2-(1-根号2)X=0x[(1+根号2)X-(1-根号2)]=0x=0,(1+根号2)X-(1-根号2)=0x=0,x=(1-根号2)\/(1+根号2)=2倍根号2-3
(1+根号2)乘以x的平方-(1-根号2)乘以X=0怎么解
(1+√2)x^2-(1-√2)x=0 化简得,x[(1+√2)x-(1-√2)]=0 即x=0或x=(1-√2)\/(1+√2)所以方程的解为x=0或x=(1-√2)\/(1+√2)=2√2-3 ((1-√2)(1+√2)=-1)
(1+根号2)x平方-(1-根号2)x等于0
解:(1+根号2)x平方-(1-根号2)x等于0,X[X[(1+根号2)x-(1-根号2)]等于0,X=0,X=-3+根号2
(1+根号2)x平方-(1-根号2)x等于0
解原式:x[(1十根号2)x-1十根号2)=0 x=0,x=-3-2根号2
(1+√2)X²-(1-√2)X=0 如何解
因为:(1+√2)X²-(1-√2)X=0 所以:(1+√2)X²=(1-√2)X X=0
(1+根号2)x平方-(1-根号2)x等于0 用一元2次方程的因式分解法接解
X有两个值,分别为0和2倍根号2-3
(1+根号2)x方-(1-根号2)x=0 (巧算)
(1+根号2)x方-(1-根号2)x=0 则(1+根号2)(根号2-1)x方-(1-根号2)(根号2-1)x=0 x²+(√2-1)²x=0 x[x+(√2-1)²]=0 所以x=0或x=-(√2-1)²
(1+根号2)x方-(1-根号2)x=0
您好:(1+根号2)x方-(1-根号2)x=0 两边乘(√2-1)(√2+1)(√2-1)x²-(1-√2)(√2-1)x=0 (2-1)x²+(2-2√2+1)x=0 x²+(3-2√2)x=0 x(x+3-2√2)=0 x1=0 x2=2√2-3 如果本题有什么不明白可以追问,如果满意请点击“选为...
解方程(1+根号2)x^2-(3+根号2)x^2+根号2=0
(1+根号2)x^2-(3+根号2)x^2+根号2=0,化简-2x^2+根号2=0,x=+正负四次根号2\/根号2。(1+根号2)x^2-(3+根号2)x+根号2=0分解因式,[(1+根号2)x-1][(1+根号2)x-根号2]=0。所以x1=根号2-1;x2=根号2
(1+根号2)X平方-(3+根号2)X+根号2=0解一下..题目绝对真确. 题目真确!没...
[(1+根号2)X-1]*(X-根号2)=0 X1=-1+根号2 X2=根号2
