Question

can x^2-7x+22 be foiled?

Answer 1

no

Answer 2

so quadratic formula?

Answer 3

22= 2*11, 1*22 only

Answer 4

yup

Answer 5

thanks

Answer 6

I think you mean factored. And yes it can be factored

Answer 7

how?

Answer 8

I could show you but you probably wouldn't understand my steps

Answer 9

yeah this is just college algebra stuff

Answer 10

it cannot be factored.

Answer 11

agreene, I can prove that it can be factored. The question is, "Can you prove that it cannot be factored?".

Answer 12

By the way, I'm aware that x is complex.

Answer 13

it can be factored!

Answer 14

2 vs 1. You're losing again agreene

Answer 15

I cannot see a way it can be factored, but I am admittedly not good at such things.

Answer 16

so if i post what i get hero can u make sure its right ill use quadratic formula

Answer 17

with the foil method, this cannot be factored. can it be factored in other ways, always.

Answer 18

Whatever you get, It will be complex

Answer 19

bingo

Answer 20

yeah soo ...i

Answer 21

can you do the quadratic formula on it real quick i keep messing up

Answer 22

not foiled jus the good old x= tbut complex of course

Answer 23

I goof up with these a lot myself

Answer 24

If anybody is curious as to how I factored that...let me know

Answer 25

7 +/- sqrt( 49-88)
-----------------
2

Answer 26

When I expand your answer I get x^2-14x+88 did I mess something up somewheres?

Answer 27

On who's answer?

Answer 28

i was using 2 not 22 wow

Answer 29

Your answer Hero. I probably goofed something somewhere...

Answer 30

I think you did

Answer 31

can √39 be simplified? i dont think it can.. jus wanna be sure

Answer 32

Yeah I forgot the two

Answer 33

O.o just checked on mathematica and it gave me x^2-14x+88 as the expansion too

Answer 34

I just forgot to put it all over two

Answer 35

I took shortcuts when factoring. I admit

Answer 36

Yeah, just use the quadratic formula if you can't factor it using traditional methods.
