Answer:
x=1
Step-by-step explanation:
x-1=(2-x)^2
x-1=4-2x-2x+x^2
x-1=4-4x+x^2
5x+x^2=5
x^2=1
x=1
Answer:
Step-by-step explanation:
x - 1 = ( 2 - x )²
Expand the terms in the bracket
That's
x - 1 = x² - 4x + 4
x² - 4x - x + 4 + 1 = 0
x² - 5x + 6 = 0
Solve the quadratic equation
x² - 5x + 6 = 0
(x - 2) (x - 3) = 0
Hope this helps you
