解方程X^2+10x+22=6
解题X^2+10x+22=6 方程
简化
X2 + 10x + 22 = 6
重新排序条件:
22 + X2 + 10x = 6
解:
22 + X2 + 10x = 6
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 '-22' 到方程的每一侧.
22 + X2 + -22 + 10x = 6 + -22
重新排序条件:
22 + -22 + X2 + 10x = 6 + -22
结合相似条件: 22 + -22 = 0
0 + X2 + 10x = 6 + -22
X2 + 10x = 6 + -22
结合相似条件: 6 + -22 = -16
X2 + 10x = -16
增加 '-10x' 到方程的每一侧.
X2 + 10x + -10x = -16 + -10x
结合相似条件: 10x + -10x = 0
X2 + 0 = -16 + -10x
X2 = -16 + -10x
简化
X2 = -16 + -10x
重新排序条件:
16 + X2 + 10x = -16 + -10x + 16 + 10x
重新排序条件:
16 + X2 + 10x = -16 + 16 + -10x + 10x
结合相似条件: -16 + 16 = 0
16 + X2 + 10x = 0 + -10x + 10x
16 + X2 + 10x = -10x + 10x
结合相似条件: -10x + 10x = 0
16 + X2 + 10x = 0
无法确定此方程的解.
