2014年1月9日 · x²－4x＋1＝0的配方法解答过程如下：（1）把1化成4-3：x²-4x+4-3=0（2）x²-4x+4可以组成一个完全平方式： (x-2)²=3（3）两边同时开根号.

2023年11月10日 · To solve the equation x^2 - 4x + 1 = 0, we can use the quadratic formula. For an equation of the form ax^2 + bx + c = 0, the quadratic formula is given by x = (-b ± √(b^2 - 4ac)) / (2a). In this case, a = 1, b = -4, and c = 1. Substituting these values into the quadratic formula, we get: x = (-(-4) ± √((-4)^2 - 4(1)(1))) / (2(1))

x^{2}+4x+1=0 这样的二次方程式可通过转换为完全平方形式来求解。 要化为完全平方形式，等式必须先转换为 x^{2}+bx=c 的形式。

2011年1月11日 · 解：因为x^2-4x+1=0 ， 所以 x-4+1/x=0 ，即 x+1/x=4 所以（x+1/x）^2=16，即 x^2+2+1/x^2=16 所以x^2+1/x^2=14

先由x^2-4x+1=0移项得x^2+1=4x,再将x^2+1=4x除以x得x+1/x=4.两边平方得(x+1/x)^2=16 拆开得x^2+1/(x^2)+2=16 移项得x^2+1/(x^2)=14

Use the quadratic formula to find the solutions. −b±√b2 −4(ac) 2a - b ± b 2 - 4 (a c) 2 a. Substitute the values a = 1 a = 1, b = 4 b = 4, and c = 1 c = 1 into the quadratic formula and solve for x x. −4±√42 −4 ⋅(1⋅1) 2⋅1 - 4 ± 4 2 - 4 ⋅ (1 ⋅ 1) 2 ⋅ 1. Simplify. Tap for more steps... Simplify the expression to solve for the + + portion of the ± ±.

这个可以这样算,比较简便 x^2-4x+1=0所以x不等于0,两边都除以x得到x+1/x=4两边同时平方得x^2+1/x^2+2=16 所以x^2+1/x^2=16-2=14
