Question

QUADRATIC EQUATIONS
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.

0 = x2 + 5x + 6
0 = x2 + 4x + 4
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 + 4x + 4 different from y = x2 + 5x + 6?

Answer 1

0 = x2 + 5x + 6
(x + 2)(x + 3) = 0
x = -2 or -3

0 = x2 + 4x + 4
(x + 2^2 = 0
x = -2

Answer 2

first equation will open upwards and will intersect the x-axis at x = -2 and x=-3
second equation has a double root = -2
it will open upwards and the bottom of graph will touch x-axis at x = -2

Answer 3

That is part two right?

Answer 4

yes
