Answer:

x=1, 5

Step-by-step explanation:

0 = 4(x - 3)^2 - 16

Add 16 to each side

0+16 = 4(x - 3)^2 - 16+16

16  = 4(x - 3)^2

Divide each side by 4

16/4 = (x-3)^2

4 =  (x-3)^2

Take the square root of each side

±sqrt(4) = sqrt( (x-3)^2)

±2 =  (x-3)

Add 3 to each side

3±2 =  x-3+3

3+2 =x   so x=5

3-2 =x   so x=1

d
