Question

(2x – 1)2 – (x – 1)2



​

Answer 1

Step-by-step explanation:

(2x+1)(2x+1)=4x^2+4x+1

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

4x^2+4x+1=x^2+2x+1

Subtract 1 from both sides

4x^2+4x=x^2+2x

Subtract x^2 from both sides as well as 4x

3x^2=-2x

Divide by 3x the x’s cancel and you get

x= -2/3

The final solutions are

x=0 and x=-2/3
