Question

help

Answer 1

so find x = -b/2a where a is the coefficient of the x^2 term and b is the coefficient of the x term

Answer 2

6

Answer 3

-b/2a = -(-6)/(2*2) = ?

Answer 4

solve for a or B?

Answer 5

x = -b/(2a)

you are asked to find x, so simply plug in a and b to find x

Answer 6

-6

Answer 7

b = -6
a = 2

-b/(2a) = ?

Answer 8

-12/(2x1)

Answer 9

-12/2

Answer 10

-6

Answer 11

@Vocaloid

Answer 12

you might be doing a/2b instead of b/(2a)

-b/(2a) = -(-6)/(2*2) = -(-6)/4 = 3/2 = your ans

Answer 13

okay and b is 12 correct?

Answer 14

b = -6

Answer 15

and a is 2?

Answer 16

yes

Answer 17

it is dalse

Answer 18

hm.

Answer 19

i put it into mathway and it is saying that the statement is false

Answer 20

that's odd, when I graph the equation it gives me x = (3/2) as the axis of symmetry :S

Answer 21

i don't know i put it into mathway with the substitutions and it says false

Answer 22

what exactly are you entering? can you show me your screen?

Answer 23

Huh. Mathway is sometimes weird. Using good old-fashioned algebra gives me 3/2 though, you can also verify this by graphing the original equation.

Answer 24

Okay sounds good, so the answer is 3/2

Answer 25

yes
