Question

x^2+18x-208=0

Answer 1

\[x^2+18x-208=0\]

Answer 2

what multiplies to -208 but adds to 18?

Answer 3

What are the factors of -208?

Answer 4

Have you factored it yet?

Answer 5

i',M CONFUSED :(

Answer 6

Always multiply A and C together

Answer 7

in this case its 1 x -208 so it remains the same

Answer 8

Do you get that much?

Answer 9

Yes.

Answer 10

It could be 13 * 16
OR any combination of
26 * 8 or
52 * 4

Answer 11

-26 & +8??

Answer 12

Which two numbers add up to 18 and multiply to -208?
-8 and 26
Rewrite the expression as (x−8)(x+26)

Answer 13

You had the signs flipped

Answer 14

Now that we have the two equations you want to set it to 0 because the equation (overall equation) sets it equal to 0 so...
x-8=0
x+26=0

solve.

Answer 15

8 n 12?

Answer 16

what? no lol you are thinking too hard xD just solve the equations SPERATELY

Answer 17

x-8=0
isolate x

Answer 18

8 n 12 r da final ans...

Answer 19

no they are not...

Answer 20

8 is right
12 is not

Answer 21

x+26= 0
isolate x...

Answer 22

12 is right
cuz
18x = y^2
18(8) = y^2
144 = y^2
12 = y
and at back of the book its written 8 n 12 now I can be wrong but not the book I guess :/

Answer 23

:/

Answer 24

@UnkleRhaukus what am i doing wrong :/

Answer 25

Answer 26

Does
(26)^2 + 18(26) - 2208 = 0?
