Question

Part 1: Solve each of the quadratic equations below. Show your work.

x2 - 16 = 0 and x2 = -2x + 24

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

it is good

Answer 2

Okay but I am not sure how to do the rest :(

Answer 3

b) the solutions represent the x-intercepts or the zeros

Answer 4

with the another equation you can do this

Answer 5

x2 = -2x + 24 => x2+2x-24=0 from here you could factor or use the quadratic formula

Answer 6

So is that x2 = -2x + 24 then? I need that answered :) I am not 100% sure how to do this

Answer 7

yes x2 = -2x + 24 is the same that x2+2x-24=0 from here you can factor and get (x+6)(x-4) so the solutions are x=-6 and x=4

Answer 8

it is the same answer for the b part

Answer 9

now for the c) part you can use this

Answer 11

in this page u can make the graph and see how the graphs alike or differ

Answer 12

I don't know how to use this :( sorry.

Answer 13

ok i will atach the file

Answer 14

the red one is x2+2x-24

Answer 15

well the vertex (the minimum point on the graph) are diferent and one of the zeros are diferent

Answer 16

i will leave take kare

Answer 17

Thanks so much!!!!
