Which of the following expressions are perfect-square trinomials? Check all of the boxes that apply.
What method would you choose to solve the equation 2x2 – 7 = 9? Explain why you chose this method.
/Explanation: I would use the square root property of equality. Because there is no x term, I would just add and divide to get x2 by itself. Then I would take the square root. Which points did you include in your response? Check all of the boxes that apply.Use the square root property of equality.There is no x term.Add and divide to isolate x2.
Now, write x² - 16x + 64 = -8 as (x - 8)² = -16✔ (x - 8)² = -8(x - 16)² = -16(x - 16)² = -8
