X^2+x^2=90.25

解方程X^2+x^2=90.25

解题X^2+x^2=90.25 方程

简化
X2 + x2 = 90.25

解：
X2 + x2 = 90.25

求解变量 'X'.

移动所有含x 的放右边，所有其它条件放左边.

增加 '-1x2' 到方程的每一侧.
X2 + x2 + -1x2 = 90.25 + -1x2

结合相似条件: x2 + -1x2 = 0
X2 + 0 = 90.25 + -1x2
X2 = 90.25 + -1x2

简化
X2 = 90.25 + -1x2

重新排序条件:
-90.25 + X2 + x2 = 90.25 + -1x2 + -90.25 + x2

重新排序条件:
-90.25 + X2 + x2 = 90.25 + -90.25 + -1x2 + x2

结合相似条件: 90.25 + -90.25 = 0.00
-90.25 + X2 + x2 = 0.00 + -1x2 + x2
-90.25 + X2 + x2 = -1x2 + x2

结合相似条件: -1x2 + x2 = 0
-90.25 + X2 + x2 = 0

无法确定此方程的解.
