Question

Can someone help me with #2 plz

Answer 1

2

Step-by-step explanation:

4x^2-16x+16=0

factor out 4 because it is a common factor

4(x-2)^2

x-2=0

x=2

Answer 2

Step-by-step explanation:

4x2 - 16x + 16 = 0

4x2 - 8x - 8x + 16

4x (x - 2) - 8(x - 2)

(x-2) (4x - 8) = 0

x - 2 = 0

x = 2

4x - 8 = 0

4x = 8

x = 8/ 4 = 2
