5x²-2x=x²+2x-1用因式分解法？

Question

如题所述

Answer 1

解：5X＾2一2x一X＾2一2x十l＝0
4X＾2一4x十l＝0
（ 2X一1）＾2＝0
2X一1＝O
2X＝1
X＝l／2

Answer 2

5ⅹ^2一2x=x^2+2x一1
4x^2一4x+1=0
(2x一1)^2=0
∴x1=x2=1/2。

Answer 3

5x^2一2x=x^2+2x一1
4x^2一4x+1=0
(2x一1)^2=0
所以2X一1=0
所以x=1/2

Answer 4

5x² - 2x = x² + 2x - 1
4x² - 4x + 1 = 0
(2x - 1)² = 0
x = 1/2

Answer 5

5x^2-2x=x^2+2x-1
4x^2-4x+1=0
(2x-1)^2=0
x=1/2
