<h2>Steps:</h2>
So for this, we will be completing the square to solve for m. Firstly, subtract 8 on both sides:

Next, divide both sides by 2:

Next, we want to make the left side of the equation a perfect square. To find the constant of this perfect square, divide the m coefficient by 2, then square the quotient. In this case:
-8 ÷ 2 = -4, (-4)² = 16
Add 16 to both sides of the equation:

Next, factor the left side:

Next, square root both sides of the equation:

Next, add 4 to both sides of the equation:

Now, while this is your answer, you can further simplify the radical using the product rule of radicals:
- Product rule of radicals: √ab = √a × √b
√12 = √4 × √3 = 2√3.

Answer:
Step-by-step explanation:13.82, 14.47, 20.10
111 would be the y-intercept. This is because 111 is on the y-axis.
Answer:
(0,-2)
maximum
Step-by-step explanation:
-x∧2-2 = -1 (x∧2) -2
so the vertex should be (0,-2)
As it is negative for the x∧2, so the graph opens downwards. So, the vertex is a maximum.
