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 1

i did part 1 and 2 i need 3

Answer 2

here's my work

Part 1:

1st equation
x^2−25=0
x^2=25
x=−5 or x=5

2nd equation second one
x^2=2x+15
x^2−2x−15=0
x=5 or x=-3


Part 2:
The zeros are where the graph of y=x2−25 cross the x axis
same for y=x^2−2x−15

Part 3:
