Answer 1

@adam.bloedel

Answer 2

(a+b)(a-b)=a²-b²

Answer 3

Seems like a binomial.

Answer 4

sorry i dont really get that this is really hard for me and i know that is a binomial

Answer 5

Since its a binomial how can it be a Trinomial.

Answer 6

thank you so so so much :)

Answer 7

can you help on one more pwease?

Answer 8

Welcome :) and ill see if I can

Answer 9

okay here it is
Find the product of (x + 5)(x - 5).

x2 - 10x + 25

x2 + 10x + 25

x2 - 25

x2 + 25

im guessing its the last one

Answer 10

(a+b)(a+b) = (a+b)² = a²+2ab+b²

Answer 11

I just wrote that lol

Answer 12

Answer 13

its the first one right?

Answer 14

you know what FOIL is?

Answer 15

um sort of

Answer 16

First
Outside
Inside
Last
Multiply the first terms in each bracket
Then Multiply the outside terms, Inside then last.

Answer 17

i still think it is the first one

Answer 18

x2 is x^2 right as in x squared?

Answer 19

yeah sorry about that

Answer 20

(x - 5)(x + 5)
so x(x) + x(5) - 5(x) - 5(5) by foil

Answer 21

Then you sub it to x² + 5x - 5x + 25 then you combine like terms to get your answer.

Answer 22

i got the last one thank you so much love you are a lifesaver :)

Answer 23

NOOO you should \[X ^{2}-25\]

Answer 24

wait I might of made a mistake did u get it right?

Answer 25

uh oh.... i already submitted it and got an 80 but thats fine thanks

Oh just remember foil, substitute and combine the like terms and you should be fine. :)
