解方程x^2-6x=0
问题描述:
解方程x^2-6x=0
还有x^2-4x+4=0,x(x-2)=3(x-2),16(2x-1)^2=25(x-2)^2
答
程x^2-6x=0
x(x-6)=0
x=0 或者6还有x^2-4x+4=0,x(x-2)=3(x-2),16(2x-1)^2=25(x-2)^2x^2-4x+4=0 x-2=0x=2x(x-2)=3(x-2),x²-2x =3x-6x²-5x+6=0(x-2)(x-3)=0x=2 或者3 16(2x-1)^2=25(x-2)^216(4x²-4x+1)=25(x²-4x+4)64x²-64x+16=25x²-100x+10039x²+36x-84=013x²+12x-28=0(13x-14)(x+2)x=14/13 或者-2
