Question

Simplify the given expression: (-2x2 - 9x + 17) - (16x2 + 17x - 1)

Answer 1

after doing so many questions. y cant u still do it on ur own??

Answer 2

show me some of ur work, we are not here to jst provide ans

Answer 3

ok i added the 2x^2 plus the 16x2 and got -18x^2

Answer 4

yes correct

Answer 5

this is the final answer i got is -18x^2-8x+18 is this corret

Answer 6

(-2x^2 - 9x + 17) - (16x^2 + 17x - 1)
(-2-16)x^2+(-9-17)x+(17+1)
-18x^2-26x+18

Answer 7

pls check ur x part of the answer again
only that is wrong

Answer 8

@bradely let him do this himself. he almost got it

Answer 9

oh yea you add the 9 into 17 x right

Answer 10

yeah

Answer 11

yes

Answer 12

ok thank yall

Answer 13

welcome :)

Answer 14

-2xy(3xy3 - 5xy + 7y2) now on this just to make sure i got it right it will be -6x^2y^4+10x^2y^2-14xy^3

Answer 15

yes it is correct @thegreatone215
glad that u r working out some on ur own :)

Answer 16

thank you lol

Answer 17

Find p(-3) and p(5) for the function p(x) = 4x4 + 8x3 - 2x2 + 13x + 10. now i know u said try it on my own but this one is confusing

Answer 18

hi first substitute -3 for x

Answer 19

just first put -3 in the place of x in the given equation and get the answer
and then put 5 in the place of x in the given equation and get the answer

Answer 20

P(-3)=4(-3)^4+ 8 (-3)^3 -2 (-3)^2 +13(-3) + 10
now solve yur self

Answer 21

same process for P(5)

Answer 22

i got that part now i got 113,3,373

Answer 23

is that correct

Answer 24

no it is not correct
P(-3)=324-216-18-39+10
= 61 is the correct answer
there (-3)^4 means u will multiply 3 itself four times and then u will get
3 x 3 x 3 x 3 =324

Answer 25

:)

Answer 26

oh ok

Answer 27

do yall know a graph website that can graph this f(x) = –2x4 – 2x3 + 4x. cause i gotta find the end behavior
