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.
