What do you need help understanding :)

Answer 2

[9.01], [9.02]

Part 1: Solve each of the quadratic equations below. Show your work. (3 points)

x^2−25=0 and x^2= 2x+15

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

Part 3: How are the graphs alike? How are they different? (2 points)

Answer 3

\[x^2-25=0\] add \(25\) get
\[x^2=25\] take the square root, don't forget the \(\pm\) get \[x=\pm5\]

Answer 4

Describe what the solution(s) represent to the graph of each
it is where the graph crosses the \(x\) axis

Answer 5

\[x^2=2x+15\] turn in to
\[x^2-2x-15=0\] then factor

Answer 6

but how do i get part 2 and 3?

Answer 7

but i dont understand how...

Answer 8

Blah OS is running slow today. My explanation gone down the drain. Anyways, thanks Satellite :D

Answer 9

How are the graphs alike? How are they different?
this is a very ill posed question probably from something like FLVS
these are not graphs they are equations
what they mean is the graph of \(y=x^2-25\) and \(y=x^2-2x-15\)
here are some nice pictures
