Question

add
(5+6x+3x^2+9x^3)(7-6x+3x^2-9x^3)
there is too many numbers and im lost to where to start

Answer 1

is there a + sign in b/w?

Answer 2

mmm yo need to find x? right?

Answer 3

yes there is a + sign. sorry im have problems with my computer

Answer 4

-81 x^6-99 x^4+18 x^3+12 x+35

Answer 5

And here you answerd your question.

Answer 6

ADD LIKE TERMS.

Answer 7

5+6x+3x^2+9x^3 + 7-6x+3x^2-9x^3

Answer 8

cyter is wrong

Answer 9

well I reduce the operation ...6x^2+12 ....mm

Answer 10

YEs right^

Answer 11

when i collect like terms i get 1488 is that right?

Answer 12

Impossible

Answer 13

i must did something wrong then crap

Answer 14

there's no doubt in that. LOL

Answer 15

i know i add it wrong and crap stupid thing sorry

Answer 16

I showed you step by step in the last question you asked that was like this if you want to look at that?

Answer 17

(5+6x+3x^(2)+9x^(3))(7-6x+3x^(2)-9x^(3))

Reorder the polynomial 7-6x+3x^(2)-9x^(3) alphabetically from left to right, starting with the highest order term.
(9x^(3)+3x^(2)+6x+5)(-9x^(3)+3x^(2)-6x+7)

Multiply each term in the first polynomial by each term in the second polynomial.
(9x^(3)*-9x^(3)+9x^(3)*3x^(2)+9x^(3)*-6x+9x^(3)*7+3x^(2)*-9x^(3)+3x^(2)*3x^(2)+3x^(2)*-6x+3x^(2)*7+6x*-9x^(3)+6x*3x^(2)+6x*-6x+6x*7+5*-9x^(3)+5*3x^(2)+5*-6x+5*7)

Multiply each term in the first polynomial by each term in the second polynomial.
(-81x^(6)-99x^(4)+18x^(3)+12x+35)

Remove the parentheses around the expression -81x^(6)-99x^(4)+18x^(3)+12x+35.
-81x^(6)-99x^(4)+18x^(3)+12x+35

Answer 18

Elassiam ...you forgot "+" (5+6x+3x^(2)+9x^(3)+((7-6x+3x^(2)-9x^(3))

Answer 19

ok let me see what I come up with hang on

Answer 20

I put the reduce operation that was 6x^2+12 but Idknow if she want "X"

Answer 21

(5+6x+3x^(2)+9x^(3))+(7-6x+3x^(2)-9x^(3))

Reorder the polynomial 5+6x+3x^(2)+9x^(3) alphabetically from left to right, starting with the highest order term.
(9x^(3)+3x^(2)+6x+5)+(7-6x+3x^(2)-9x^(3))

Reorder the polynomial 7-6x+3x^(2)-9x^(3) alphabetically from left to right, starting with the highest order term.
(9x^(3)+3x^(2)+6x+5)+(-9x^(3)+3x^(2)-6x+7)

Remove the parentheses that are not needed from the expression.
9x^(3)+3x^(2)+6x+5-9x^(3)+3x^(2)-6x+7

Since 9x^(3) and -9x^(3) are like terms, add -9x^(3) to 9x^(3) to get 0.
0+3x^(2)+6x+5+3x^(2)-6x+7

Since 3x^(2) and 3x^(2) are like terms, add 3x^(2) to 3x^(2) to get 6x^(2).
6x^(2)+6x+5-6x+7

Since 6x and -6x are like terms, add -6x to 6x to get 0.
6x^(2)+5+7

Add 7 to 5 to get 12.
6x^(2)+12

Answer 22

6x^(2)+12

Factor out the GCF of 6 from each term in the polynomial.
6(x^(2))+6(2)

Factor out the GCF of 6 from 6x^(2)+12.
6(x^(2)+2)

Answer 23

she wont get answer for x because of the kind of equation it is
