What are the solutions of the quadratic equation 0 = 4 (x - 3) 2 - 16?

x=1,5

Step-by-step explanation:

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

add 16 to each side

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

16 = 4 (x - 3) ^2

divide by 4

16/4 = 4/4 (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+2 = x and 3-2 = x

5=x and 1=x
