11. Choose the correct answer. Find the quadratic equation in standard form given the points (-2, 0), (2,0), and (4, 6). g(x)=x²-4 | 9(x) = = 1x² - ○ g(x) = 1 1² O 2 g(x)=2x² - 4x +2

This is our quadratic equation: 5x^2 - 10x - 45 = -5 Use the completing the square method to answers the following questions.   1.You do not need to do step one for this particular quadratic.. Single choice. true false   2.After doing (or not doing) step 1, your equation looks like which one? Single choice. x^2 - 2x - 9 = -1 5x^2 - 10x - 45 = -5   3.After doing step 2, the equation looks like which one? . Single choice. x^2 - 2x = 10 x^2 - 2x + 9 = -1 x^2 - 2x = 8 x^2 - 2x - 9 = -1   4.After doing step 3 the equation looks like which one? Single choice. x^2 - 2x = 8 x^2 - 2x + 1 = 9 x^2 - 2x + 10 = 8 x^2 - 2x + 1 = 10   5.After doing step 4, the equation looks like which one?  Single choice. (x - 3)(x + 3) = 8 (x - 1)^2 = 9 (x + 1)(x - 1) = 8 (x + 3)^2 = 9   6.A radical cancels. Single choice. a logarithm division the second power   7.When you take the square root of a number you always get. Single choice. a positive or…
