11x^2=7x-4

解方程11x^2=7x-4

解题11x^2=7x-4 方程

简化
11x2 = 7x + -4

重新排序条件:
11x2 = -4 + 7x

解：
11x2 = -4 + 7x

求解变量 'x'.

重新排序条件:
4 + -7x + 11x2 = -4 + 7x + 4 + -7x

重新排序条件:
4 + -7x + 11x2 = -4 + 4 + 7x + -7x

结合相似条件: -4 + 4 = 0
4 + -7x + 11x2 = 0 + 7x + -7x
4 + -7x + 11x2 = 7x + -7x

结合相似条件: 7x + -7x = 0
4 + -7x + 11x2 = 0

开始做平放. 将所有条件除以
11 平方项的系数: 

两边除以 '11'.
0.3636363636 + -0.6363636364x + x2 = 0

将不变的条件移到右边:

增加 '-0.3636363636' 到方程的每一侧.
0.3636363636 + -0.6363636364x + -0.3636363636 + x2 = 0 + -0.3636363636

重新排序条件:
0.3636363636 + -0.3636363636 + -0.6363636364x + x2 = 0 + -0.3636363636

结合相似条件: 0.3636363636 + -0.3636363636 = 0.0000000000
0.0000000000 + -0.6363636364x + x2 = 0 + -0.3636363636
-0.6363636364x + x2 = 0 + -0.3636363636

结合相似条件: 0 + -0.3636363636 = -0.3636363636
-0.6363636364x + x2 = -0.3636363636

这个 x 项是 -0.6363636364x. 取其系数的一半 (-0.3181818182).
该平方 (0.1012396694) 并将其添加到两侧.

增加 '0.1012396694' 到方程的每一侧.
-0.6363636364x + 0.1012396694 + x2 = -0.3636363636 + 0.1012396694

重新排序条件:
0.1012396694 + -0.6363636364x + x2 = -0.3636363636 + 0.1012396694

结合相似条件: -0.3636363636 + 0.1012396694 = -0.2623966942
0.1012396694 + -0.6363636364x + x2 = -0.2623966942

一个完整的平方在左侧:
(x + -0.3181818182)(x + -0.3181818182) = -0.2623966942

一个完整的平方在左侧:
