Answer 1

www.mathway.com is a good website that will do all that work for you @CountryGurl15

Answer 2

Okay really?

Answer 3

you can factor out a y^2 in part a because all terms contain it

Answer 4

Can you just tell if those r right or not please =)

Answer 5

Answer 6

part B is wrong

Answer 7

yes those r the answers =)

part b is wrong?

Answer 9

Yup part B is incorrect (a+b)^2 = a^2+b^2 +2ab

Answer 10

How would i fix part b?

Answer 11

(x-5)^2 = x^2 + -10X + 25

Answer 12

that is what your answers looks like factored

Answer 13

oh okay so what would the correct answer be?

Answer 14

check my previous message

Answer 15

you need to make the 10 x positive by changing something.....

Answer 16

adding 5?

Answer 17

Nooooooo

Answer 18

no inside the brackets

Answer 19

(x-5)^2 to (x+5)^2 that's what i meant =)

Answer 20

yeah nice job

Answer 21

okay so that would make 10 positive ? =)

Answer 22

yes, one way to check is to re distribute

Answer 23

okay so it will be (x+5)^2 =x^2 +10x +25 ?

Answer 24

yup

Answer 25

okay now what? =)

Answer 26

so wait the factored version of x^2 +10 +25 is (x+5)^2 ?

Answer 27

or (x+5)(x+5)

Answer 28

okay that ^^ is the correct answer for part b?

Answer 29

everything else looks good

Answer 30

Awesome! thx so much for all the help! =)
