2. Use the part of the Quadratic Equation called the Discriminant to answer the following questions.
a. What is the value of the discriminant for x2 + 4x + 7 = 0
b. How many solutions will this equation have and how do you know?
c. What is the value of the discriminant for x2 – 16x + 64 = 0
d. How many solutions will this equation have and how do you
know?
1
3. Use the entire Quadratic Equation to find the solution to the
equation. Show your steps! Only showing the final answer is not
worth any credit.
X2 + 6x + 8 = 0

1.0

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

when rotating a figure 180 degrees, imagine that you are able to take the figure and turn it clockwise or counterclockwise around a center point. to rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y). start by using a coordinate grid with coordinates for each vertex of the figure. the center point of the coordinate grid is located at (0, 0), which is what you will rotate the figure around. write down the original coordinates of the shape you are going to rotate. then, apply the rule. for example, coordinate (1, 2) becomes (-1, -2). another example would be, coordinate (-4, -2) becoming (4, 2). after you change each original coordinate to the rotated coordinate, you will draw your new figure.
