Question

ALGEBRA HELP PLEASE

I need help putting this in standard form.

-2n^2 (5n - 9 + 4n^2)
= 10n^3 + 18n^2 -8n^4

Answer 1

its -10n^3

Answer 2

In standard form?

Answer 3

i can :)

Answer 4

no i meant, you typed 10^3 at the top, but its meant to be -10^3 and i cant change it to standard form remember? sorrry!

Answer 5

meant to be -10n^3

Answer 6

@ArifL Can you help me put it in standard form?

Answer 7

put it in order from biggest exponent to smallest exponent

Answer 8

do you know which term has the biggest exponent?

Answer 9

No I don't

Answer 10

the exponent is the little number in the upper right of the variable n

Answer 11

I know what the exponent is but I don't know how to put my answer in standard form.

Answer 12

put the terms in order from biggest exponent down to smallest

Answer 13

-8n^4, -10n^3, 18n^2 is that correct?

Answer 14

yes, but they are added

Answer 15

so -8n^4 + 10n^3 + 18n^2 ?

Answer 16

I got them in order from largest to smallest exponent but how does that put it in standard form?

Answer 17

ok, except it's -10n^3 not +10n^3

Answer 18

-8n^4, -10n^3, 18n^2 so like that?

Answer 19

yes, but they are added
-8n^4 + -10n^3 + 18n^2
though if you add a negative , you can write it this way
-8n^4 - 10n^3 + 18n^2

that is standard form

Answer 20

if you had
1+2x
standard form is
2x+1
(the exponent on the "x" is 1, and that is the biggest (and only) exponent.. so 2x goes first)

Answer 21

@phi Thanks :) Can you help me with a few more??
