Question

Put the equation below in the form ax2 + bx + c = 0. Enter exponents using the caret ( ^ ). For example, you would enter 4x2 as 4x^2.

x2 + 2x + 9 = 2

Answer 1

i need help.

Answer 2

x2 + 2x + 9 = 2

Answer 3

you need to convert it to
ax2 + bx + c = 0

Answer 4

right ?

Answer 5

yes.

Answer 6

first make the right side 0
subtract 2 both sides

Answer 7

x2 + 2x + 9 = 2

x2 + 2x + 9-2 = 2-2

x2 + 2x + 7 = 0

Answer 8

is thats the answer.

Answer 9

u think.. x2 has no co-efficent ?... is that throwing u off ?

Answer 10

so then it would 2x^2

Answer 11

it is in form
ax2 + bx + c =0

so that must be d answer

Answer 12

nope

x^2 \(\ne \) 2x^2

Answer 13

x^2 = 1x^2

Answer 14

when you dont see any co-effecient, you can think of it as :

x^2 = 1x^2

so co-effecient is 1

Answer 15

yea so its x2 + 2x + 7 = 0

Answer 16

yes.
its same as,

1x2 + 2x + 7 = 0

here :
a =1
b =2
c = 7

Answer 17

oh'k ill plug it in now.

Answer 18

good luck :)
careful...
it asks you to enter exponents using ^ sign..

Answer 19

oh i got it.
thank you.

Answer 20

np..

Answer 21

will you help me with the next one?

Answer 22

sure post it :)

Answer 23

x2 - 2 = -2x2 + 5x

Answer 24

add 2x2 both sides

Answer 25

lets do things that make right side = 0

Answer 26

2x^2-x^2=5x

Answer 27

?

Answer 28

where did -2 go...
we will go step by step... so that it becoems clear

Answer 29

oh'k.

Answer 30

x2 - 2 = -2x2 + 5x

add 2x2 both sides

x2 - 2 + 2x2 = -2x2 + 5x + 2x2

x2 + 2x2 - 2 = 5x

3x2 - 2 = 5x

subtract 5x both sides

3x2 - 2 - 5x = 5x - 5x

3x2 - 5x - 2 = 0

Answer 31

yay!
i got it right.

Answer 32

:) glad to hear.. .

Answer 33

3x2 + 27x + 60 = 0?
