解方程:(1-3x)^2+(2x-1)^2=13(x-1)(x+1)

解方程:(1-3x)^2+(2x-1)^2=13(x-1)(x+1)
解方程:(1-3x)^2+(2x-1)^2=13(x-1)(x+1)

解方程:(1-3x)^2+(2x-1)^2=13(x-1)(x+1)
(1-3x)²+(2x-1)²=13(x-1)(x+1)
1-6x+9x²+4x²-4x+1=13x²-13
-10x+2=-13
10x=15
x=3/2

(1-3x)^2+(2x-1)^2=13(x-1)(x+1) 1-6x+9x^2+4x^2-4x+1=13(x^2-1)=13x^2-13 10x=2+13=15 x=1.5
