数学难题```求高手帮忙X的平方=1.695的平方+（X-1.075）的平方X的平方=105125的平方+（X-0.525）的平方

Answer 1

x^2=1.695^2+(x-1.075)^2
x^2=1.695^2+x^2+1.075^2-2.15x
x^2=(1+695/1000)^2+x^2+(1+75/1000)^2-2.15x
0=(1+695/1000)^2+(1+75/1000)^2-2.15x
0=1+(695/500)+(695/1000)^2+1+(75/500)+(75/1000)^2-2.15x
0=1000+695*2+695*695+1000+75*2+75*75-2150x
0=1000+695*2+695*695+1000+75*2+75*75-2150x
0=1000+1390+483025+1000+150+5625-2150x
0=200+278+96605+200+30+1125-430x
0=98438-430x
x=98438/430
x=49219/215
x^2=105125^2+(x-0.525)^2
x^2=105125^2+x^2+0.525^2-1.05x
0=105125^2+0.525^2-1.05x
0=21025^2+0.105^2-0.21x
0=(21000+25)^2+(105/1000)^2-0.21x
0=441000000+625+25*21000*2+(105/1000)^2-0.21x
0=441000000+625+1050000+(105/1000)^2-0.21x
0=442050625+(105/1000)^2-0.21x
0=442050625*1000+105*105-210x
0=4420506251000+11025-210x
0=88410125000+2205-42x
0=88410127205-42x
x=88410127205/42
