Question

4y^2-3{2y^2-[(4y^2 - y + 2) - (3y^2 + 2y - 5)]}

Answer 1

okay imm stuck on a part

Answer 2

Heres my work :
4y^2 (- 6y2) (-12y^2 - 3y + 6) (-9y^2 + -6y) (-15)
(4y^2 - 6y^2 - 12y^2 - 9y^2) (-3+-6y) (6 - (-15)

Answer 3

this is tricky

Answer 4

(-3 + 6y) is supposedd to be (-3y + -6y)
I collected the like terms, but i think im doing something wrong.
the answer is supposed to be y^2 - 9y +21

Answer 5

so whats the objest we have to get?

Answer 6

just simplifying

Answer 7

ok

Answer 8

(16y-36y-144y-81y)(-9y)(21)

Answer 9

k got it almost simplied

Answer 10

I have to multiply it? lol ahh omg i was trying to add / subtract

Answer 11

lol

Answer 12

is it because of the y^2?

Answer 13

and yes

Answer 14

the answer sheet says its supposed to be y^2 - 9y + 21

Answer 15

well i have the 9y+21 part

Answer 16

what i did was subtract 4y2 - 6y2 and it gave me 2 and then 12y2 - 9y2 and it gave me 3 and i subtracted that and it gave me -y2
but it doesnt sound right

Answer 17

because the y2 is supposed to be positive

Answer 18

no no thats right

Answer 19

it turns postive

Answer 20

oh whaat the heck lol...

Answer 21

ya

Answer 22

thanks :)

Answer 23

so u should have y^2-9y+21

Answer 24

thx for medal

Answer 25

yup.. but okay if i subtracted 12 - 9 its 3 right and 4-6 -2?
-2 - 3 = 5?

Answer 26

yw

Answer 27

Answer 28

peace

Answer 29

i have a question about getting y^2...

Answer 30

i can help you with that awser

Answer 31

what i did was (-2y^2 + 3y^2) and got y^2 is that correct?

Answer 32

but i dont get it because i worked it out and
it said 4y^2 - 6y^2 -(-12y^2 - 3y + 6) - (9y^2 - (-15)

Answer 33

4y2−3(2y2−(4y2−y+2−(3y2+2y−5)))
Distribute:
=4y2+(−3)(2y2)+(−3)(−4y2)+(−3)(y)+(−3)(−2)+(−3)(3y2)+(−3)(2y)+(−3)(−5)
=4y2+−6y2+12y2+−3y+6+−9y2+−6y+15
Combine Like Terms:
=4y2+−6y2+12y2+−3y+6+−9y2+−6y+15
=(4y2+−6y2+12y2+−9y2)+(−3y+−6y)+(6+15)
=y2+−9y+21
Answer:
=y2−9y+21

Answer 34

thanks !

Answer 35

yup
