Question

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

x2 – 36 = 0 and x2 = 8x – 12

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

K for part 1, all you have to know for the first problem is what factors when multiplied eqaul -36, do you know that? :)

Answer 2

ummm i want to say... 16 x 2

Answer 3

-16

Answer 4

That doesn't equal -36 when multiplied, but -6*6 does :)

Answer 5

xd brain fart. i was thinking of some thing else.

Answer 6

so how would it be solved?

Answer 7

Now all you would do is (x-6)(x+6) to factor the quadratic equation. Wait is that what you needed?

Answer 8

oh and how would you do the 2nd one?

Answer 9

K so we have x^2= 8x-12. We can make this x^2-8x+12=0

Answer 10

Now you need to find out what factors when multiplied to 12, add up to -8. Can you think of anY? :)

Answer 11

ohhh!! 4 -4?

Answer 12

sooo....(x+4) (x-4)

Answer 13

Not necessarily. 4*-4=-16. We need two numbers like -6*-2 that equal 12 and add up to -8 :) Since those two numbers are it we can factor our quadratic equation as
(x-6)(x-2)

Answer 14

oh....jumped the gun there. lol but thanks!!

Answer 15

No problem :)
