Question

0=(x-1)^2-4 show work <33

Answer 1

Answer:

x=-1,3

Step-by-step explanation:

0=(x-1)^2-4

Add 4 to each side

0+4=(x-1)^2-4+4

4 = (x-1)^2

Take the square root of each side

sqrt(4) = sqrt((x-1)^2)

±2 = x-1

Separate into 2 equations

2 = x-1         -2 = x-1

Add 1 to each side

2+1 = x-1+1     -2 +1 =x-1+1

3 =x                     -1 =x

There are two solutions

x=-1,3
