To solve 9x^2-12x+4=49 by using the Square Root Property, you would first rewrite the equation was as

A. 9x^2-12x-45=0
B.(3x-2)^2=+/-49
C.(3x-2)^2=7
D.(3x^2)^2=49

1 answer

strange question, clearly

9x^2 - 12x + 4 = 49
(3x - 2)^2 = 49
3x - 2 = ± 7
3x = 2 ± 7
3x = 9 or 3x = -5
x = 3 or x = -5/3

so I guess they just wanted the 2nd line .
