Question

Write x^2 − 8x + 13 = 0 in the form (x − a)^2 = b, where a and b are integers.

(x − 4)2 = 3
(x − 3)2 = 2
(x − 2)2 = 1
(x − 1)2 = 4

Answer 1

@jhonyy9

Answer 2

do you know formula (a-b)^2 = ?

Answer 3

yeah i think so

Answer 4

write it here please

Answer 5

yeah one sec

Answer 6

courage just like a first step

Answer 7

ya that will help

Answer 8

Would it be like this?
(x-1)^a = 8

Answer 9

no

Answer 10

damnit ik where i messed up

Answer 11

you need to know formula (a-b)^2 = ?

Answer 12

the a would be 2

Answer 13

so nvm then ig idk it

Answer 14

ya i think so

Answer 15

a=2 not is right

Answer 16

hold on

Answer 17

it would be like this then cause i messed up
(x-1)^2 = 8 right.....????????

Answer 18

and so how will get the 13 ?

Answer 19

ATTENTION please !

Answer 20

I am paying attention!!!!!! i was looking back at the damn problem!!!!

Answer 21

rewrite it in this way

x^2 - 2*4x +13+3-3 = 0 bc. x^2 -8x +16 = (x-4)^2

Answer 22

from this result a=4

and so b = ?

Answer 23

I am just confused now this is retarded

Answer 24

ok. looke please

(a-b)^2 = a^2 -2ab +b^2

yes ?

Answer 25

ig

Answer 26

so fro you can making from this x^2 -8x +13 perfect square of

(x-4)^2 = x^2 -2*4x +16

what you need to do with 13 ?

Answer 27

you need adding to 13 a 3

Answer 28

Iḿma be honest i am completely confused and this is everywhere

Answer 29

but for you can adding this 3 you need subtracting it too for this expression not being modified

Answer 30

idk what to do and not to be rude but you are making this problem go everywhere

Answer 31

first of all you need making from x^2 -8x +13 a square perfect

yes ?

Answer 32

this will be (x-a)^2

Answer 33

ok

Answer 34

you can rewriting this x^2 -8x +13 in this form x^2 -2*4x +13

yes ?

Answer 35

and bc. formula (a-b)^2 = a^2 -2ab +b^2 this mean that in place of b^2 you need getting 16 what is the square of 4

Answer 36
