Question

Solve each of the quadratic equations below. Show your work.

x2 - 16 = 0

Part 2: Describe what the solution(s) represent to the graph of each.

Part 3: How are the graphs alike? How are they different?

Answer 1

x^2 - 16 = 0
x^2 = 16
x = + or - 4

Answer 2

there have to 2 equations to answer part 2 & 3

Answer 3

For part 2,

x = 4 or x = -4

and they represent the points where the graph intersects the x axis.

For part 3, I can see that there should have been two equations.
