Quadratic equations are not nol in the form f(x) = ax²+bx+c to find (h, k). Begin by completing the square on a(x-h)² + k. We can complete the square on a the terms containing x² and x. EXAMPLE 6-3 Find the vertex. · y = x² - 6x-2 y = x² - 6x-2 y = |x² - 6x + (99] 2 - 2 + ? We need to balance putting +()² = 9 inside the parentheses by adding -9 outside the parentheses. y = (x² - 6x + 9) - 2-9 y = (x - 3)² - 11 The vertex is (3,-11).

When you added k^3 + (k+1)^3 + (k+2)^3 I got 3x^3 + 9x^2 + 15x + 9. I dont know how you got 3k^3 + 9k^2 + +9k + 9. I double checked it with symbolab too, so I really have no clue how you got that answer.

Please help me to answer the question below, thank you
1-16x^2 Can you tell me why we square the 1? Can you tell me why we bring 16x^2 down to (4x)^2 ? I am trying to understand why you would take those steps. I kinda understand that you need to make 1 into a square therefore 1^2. Please give me any insight into why these steps are taken. I know it's the difference of square formula.
