Answer 1

把（X-2.731）^2拆开成X^2-2*2.731*X+2.731^2
两边消掉X^2,再移位，得2*2.731*X=12.507^2+2.731^2
最后算得X=（12.507^2+2.731^2)/（2*2.731）

Answer 2

计算过程:
x²=12.507²+（X-2.731）²
x²=12.507²+x²-2*2.731*x+2.731²
2*2.731*x=12.507²++2.731²
x=(12.507²++2.731²)÷2÷2.731

Answer 3

解 x²=12.507²+x²-2x*2.731+2.731²
5.462x=12.507²+2.731²
x=(12.507²+2.731²)/5.462
这个是解题步骤哦，具体结果你可以用计算器算

Answer 4

x²=12.507²+x²+2.731²-2*2.731*x
0=12.507²+2.731²-2*2.731*x
x约等于30
