Question

PLEASE HELP! Use completing the square to change the form of the function. f(x) = 2x^2 + 12x + 17

(If completing the square doesn't work, the quadratic formula may work)

Answer 1

Use quadratic formula:
a=2
b=12
c=17

and get

−3±0.5√ 2

Answer 2

it said this answer was wrong

Answer 3

I got ± √2/2 - 3 and it said that was wrong too

Answer 4

to change the form of the function.
f(x) = 2x^2 + 12x + 17
you might arrived at the form
f(x)=(x +____ ?)(x +______? )

Answer 5

I'm not sure...

Answer 6

I only have 1 h0ur left! please help me!!

Answer 7

any suggestions? the 2 solutions posted are somehow wrong.

Answer 8

Answer 10

Thats something I wasn't sure of @nicetomeetyou , thats exactly how the problem is written, but I assume it may be = 0 otherwise how could you solve it?

Answer 11

I mean the porblem is exactly written as ...

Use completing the square to change the form of the function. f(x) = 2x^2 + 12x + 17

Answer 12

Ok! just 1 sec...

Answer 13

f(x) = 2x^2 + 12x + 17 dive this by 2 we get
x^2+6x+ 17/2 ..now on that 6x, 6/2=3
therefore use
(x+3)^2 +17/2 -9
=(x+3)^2 -1/2 ...yes or no?
