Question

Part 1:
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

part 1, set both equations equal to each other and solve for x. If they do not turn into a quadratic you can break up mentally,use the quadratic forumla.

Answer 2

part 2??

Answer 3

so like this The first one factors into (x+2)(x+1), the second one is (x+1)(x+1).

The two quadratic equations share a common factor (x+1).

There are two ways to answer the second question. First, the simple observation that one contains 3x and the other 2x. The better answer is that the first quadratic equation has a second factor of (x+2), while the second quadratic equation has a second factor of (x+1).
