What method would you choose to solve the equation 2x2 – 7 = 9? Explain why you chose this method.

Answer:

I would use the square root property to solve the equation. Since there is no linear xterm, I can isolate the x^2 term by adding 7 to both sides and then dividing by 2. This leaves x^2 8, which can then be solved by taking the square root of both sides.
