Question

Solve each of the quadratic equations below and describe what the solution(s) represent to the graph of each. Show your work to receive full credit.

y = x2 + 3x + 2
y = x2 + 2x + 1

Part 2:
Using complete sentences, answer the following questions about the two quadratic equations above.
Do the two quadratic equations have anything in common? If so, what?
What makes y = x2 + 3x + 2 different from y = x2 + 2x + 1?

Answer 1

so you want to set both equations equal to 0, then factor them. can you do that?

Answer 3

@BTaylor thanks, yes i can do that

Answer 4

ok, so you have it factored into:
1) (x+1)(x+2) = 0
2) (x+1)(x+1) = 0
right?
So now you set both factors equal to 0:
1) x+1 = 0 AND x+2 = 0
so x = -1 and -2
2) x+1 = 0 AND x+1 = 0
so x = -1
They are different because in #2, it is a double root (you get x = -1 for both factors)

Answer 5

Oh, and on the graph, the x-values are where they intersect the x-axis.
