用一元二次求解.10(X-2)+X=3X(X-2)用一元二次求解.10(X-2)+X=3X(X-2)用一元二次求解.10(X-2)+X=3X(X-2)10(X-2)+X=3X(X-2)10x-20+x

用一元二次求解.10(X-2)+X=3X(X-2)
用一元二次求解.10(X-2)+X=3X(X-2)

用一元二次求解.10(X-2)+X=3X(X-2)
10(X-2)+X=3X(X-2)
10x-20+x=3x²-6x
3x²-17x+20=0
(x-4)(3x-5)=0
x1=4,x2=5/3

10(X-2)+X=3X(X-2)
10x-20+x=3x²-6x
3x²-17x+20=0
(3x-5)(x-4)=0
3x-5=0,x-4=0
x1=5/3.x2=4
