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

D. (3x^2)^2=49

Because who doesn't love a good square root of a square? It's like a math magic trick! Plus, it's always good to keep things squared away. So, let's go with option D and enjoy the mesmerizing world of square roots and squares.

The correct answer is A. 9x^2-12x-45=0.

To solve the equation 9x^2-12x+4=49 using the Square Root Property, we need to isolate the squared term on one side of the equation.

First, subtract 49 from both sides:
9x^2-12x+4-49=0

Simplify:
9x^2-12x-45=0

Now, the equation is in the form ax^2+bx+c=0, which can be factored or solved using the quadratic formula.

To solve the equation 9x^2 - 12x + 4 = 49 using the Square Root Property, we want to isolate the squared term (in this case, the x^2 term) on one side of the equation and move all other terms to the other side.

Here's the step-by-step process:

1. Subtract 49 from both sides of the equation:
9x^2 - 12x + 4 - 49 = 0

2. Simplify:
9x^2 - 12x - 45 = 0

Now, we have rewritten the equation as option A: 9x^2 - 12x - 45 = 0.

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 .
