Question

x 3(x 2 + 5x + 1)

Answer 1

well she said it (or he)

Answer 2

Oh, umm thanks but i odn't see that as my multiple choice :3

x^6 + 5x ^4 + x 3<--- wrong -.-
x ^5 + 5x ^4 + x 3
x ^5 + 5x ^3 + x 3

Answer 3

**don't

Answer 4

x^3 means x*x*x
x^2 means x*x

if you distribute the x^3 times each term in side the parens, the first
multiplication is x^3 * x^2 which is x*x*x*x*x
what is that using "exponents" ?

Answer 5

x^5

Answer 6

so the answer will have x^5 in it

now the next term is x^3 * 5*x
or if we rearrange that: 5* x*x*x * x
what is that using exponents

Answer 7

5x^4?

Answer 8

yes

Answer 9

Oh wait..so i add them like this

Answer 10

the last term is x^3 *1
or x*x*x*1 or just x*x*x or x^3

Answer 11

Oh i see that would be x ^3

Answer 12

yes, and the whole thing is
x^5 + 5x^4 + x^3

Answer 13

so i add them all
Oh at first i thought i had to subtract...
thank you

Answer 14

thank you the steps actualy helped.

Answer 15

There are rules, and if you get used to them, you can do these problems.

Answer 16

Yeah i need to memorize them

Answer 17

better is to understand why they work

for example, with numbers, if you had
2*(1+3)

that means you have "two" of everything inside the parens
(think of the ( ) as a package)
in other words you have 2 1's written 2*1 and two threes: 2*3
2*(1+3) = 2*1 + 2*3

that is "distributing" the 2
and that rule also works for letters.
x(1+3) = 1*x + 3*x

Answer 18

Oh yeah the only step i remeber always is distubite..
