Question

c) (1-x)(x-1)+2x = (2-x)(x - 1)​

Answer 1

Respuesta:

(1-x)(x-1) +2x = (2-x)(x-1)

(1)x+(-1)+(-x×x)+(-x)+2x = (2-x)(x-1)

x-1+(-x^2)-x+2x = (2-x)(x-1)

x-1-x^2+x = 2(x)+(2×-1)+(-x×x)+(-x*-1)

-1-x^2 = 2x+(-2)+(-x^2)+x

-1-x^2 = 2x-2 -x^2+x

-1-x^2+1 = 2x-2-x^2+x+1

-x^2 = 2x-2-x^2+x+1

-x^2 = 2x-1-x^2

-x^2+x^2 = 2x-1-x^2+x^2

0 = 2x-1

2x-1 = 0

2x-1+1 = 0+1

2x = 1

2x/2 = 1/2

x = 1/2
