Question

Find the product (2n + 2)(2n - 2)

Answer 1

\((a+b)(a-b)=a^2-b^2\)
Here a=2n, b=2
Does that help?

Answer 2

is it 4n^2 - 4?

Answer 3

yup:)

Answer 4

so if the question is find the square (6m + 7)^2 what formula is it?

Answer 5

\((a+b)^2=a^2+2ab+b^2\)
here a=6m, b=7

Answer 6

Does that help?

Answer 7

woah i think you just taught me math....

Answer 8

so its 36m^3 + 84m + 49?

Answer 9

it is 36m^2+ 84m + 49

Answer 10

well 36m^2 i mean

Answer 11

ya:)

Answer 12

so i was right?

Answer 13

yup:)

Answer 14

this is the first time I have done algebra ever really, so thanks for the help!

Answer 15

if its (2x - 6)^2 what formula?

Answer 16

"find the square"

Answer 17

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

Answer 18

here a=2x, b=6

Answer 19

working on it 1sec

Answer 20

is it 4x^2 - 8x + 36?

Answer 21

middle term is wrong

Answer 22

hmm its either 12x or 24x not sure

Answer 23

id say 24x?

Answer 24

2*2x*6=?

Answer 25

(2n)^2-(2)^2
4n^2-4

Answer 26

so it is 24x!

Answer 27

yup:)

Answer 28

Do you know how to find missing coefficient?

Answer 29

ya:)

Answer 30

ok (4d - 4)(3d - 2) = 12d^2 + ?d + 8

? = missing coefficient

Answer 31

(4d - 4)(3d - 2)
=4d(3d-2)-4(3d-2)
=12d^2-8d-12d+8

Answer 32

?d=-8d-12d

Answer 33

ohhhh i see so 4

Answer 34

nope:(

Answer 35

both the numbers are negative. so the result is also negative

Answer 36

blah its okay, How would i factor the expression 3x^3 + 3x^2 + x + 1

Answer 37

-20?

Answer 38

Yeah I should have known better
