Question

use the FOIL method to solve:
(x^2+7)(x^2+7)

Answer 1

@ParthKohli will FOIL it for you, he's an expert at this ;)

Answer 2

lol

Answer 3

FIRST

\( \color{Black}{\Rightarrow x^2 \cdot x^2 }\)

OUTSIDE

\( \color{Black}{\Rightarrow x^2 \cdot 7 }\)

INSIDE

\( \color{Black}{\Rightarrow 7 \cdot x^2 }\)

LAST

\( \color{Black}{\Rightarrow 7 \cdot 7}\)

Add them.

Answer 4

i did all that already but i came up for my final answer with 16^2+49
is that right??

Answer 5

please help!!

Answer 6

FOIL METHOD and Distributive Method are the same exact thing

Answer 7

(x^2+7)(x^2+7)
=x^2(x^2+7)+7(x^2+7)
=x^2 + 7x^2 + 7x^2 + 49
=x^2 + 14x^2 + 49

Answer 8

Well... not really.
They are the same thing, but they have different ways.

Answer 9

but dont you need to collect like terms so itd be 15x^2+49

Answer 10

And I find the way Hero did it easier.

Answer 11

Parth, they're the same. Do you want me to prove it to you?

Answer 12

dont argue answer my question please

Answer 13

No lol they're same but done in different orders :P

Answer 14

They are the same actually, @Hero is right, just a 'tweak' different.

Answer 15

ya order of proceeding if a bit different.

Answer 16

*is

Answer 17

look closely at the second step, then you'll realize they're exactly the same.

Answer 18

The main rule is the same.

Answer 19

Yeah Hero won the typing race ;)

Answer 20

your answer was wrong hero.

Answer 21

Yeah it must be x^4

Answer 22

Oops

Answer 23

thanks a lot dude -.-

Answer 24

I blame Parth, lol

Answer 25

lol

Answer 26

makes me a sad panda

Answer 27

Sorry, I wish I could make it up to you somehow

Answer 28

(5x^3+5x)(x^2+6)
answer this correctly and itll be okay xD

Answer 29

(5x^3+5x)(x^2+6)
=x^2(5x^3+5x)+6(5x^3+5x)
=5x^5+5x^3+30x^3+30x
=5x^5 + 35x^3 + 30x

Answer 30

ok what about this one?
(x^12-x^9)(x^3-10)

Answer 31

Why haven't you figured out the FOIL Method yet?

Answer 32

i have but im terrible with it and if i fail this quiz again for my online course im screwed. its just something i want to get done with

Answer 33

is this right for it?
x^15-11^12+10^9
