Question

PLEASE HELP

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

hi use quadratic formula in those two equation, do you know thw quadratic formula?

Answer 2

X^2 + 5x + 6 = 0
this can be factorised as
X^2 + 2x + 3x + 6 = 0
X(x+2) + 3 ( x + 2) = 0
(x+2) * ( x + 3 ) = 0
x = -2 or -3

For x^2 + 4x + 4,
it is factorised as
x^2 + 2x + 2x + 4 =0
this simplifies to
(x+ 2) * (x+2) =0
or (x+2)^2 =0
in both cases, x = -2

Answer 3

Thank you so much for the help

Answer 4

Thanks Mark for trying to help but i guess ishan beat u too it lol

Answer 5

try also learning to use the quadratic formula if the equation cant be factored out...

Answer 6

Quadratic formula makes sense when you cannot find the factors but it is too lengthy for small questions like this

Answer 7

hahaha ok thats great, i only want you to learn the process of solving thats why i ask you to use the formula...

Answer 8

i will :)

Answer 9

ok great...practice makes perfect..keep on practicing and solving....

Answer 10

Nikko, u hv the roots of the two equations. What abt the other questions asked??
You know their answers??
