Answer 3

You'll need to distribute

a(b - c) = ab - ac

You'll apply the distributive property to your question. It would be something like this:

a(b - c + d - f) = ab - ac + ad - af

Answer 4

can u explain it to me in numbers... thats really confusing for me

Answer 5

@sleepyjess @imqwerty

Answer 6

I did it with variables, mhmm

5(1 - 5 + 3 + 6)

we can simplify the parenthesis, but in your question we can't since they aren't like terms, so let's not simplify the parenthesis

5(1) - 5(5) + 5(5) + 5(6)
= 5 - 25 + 25 + 30
= 5 + 30
= 35

Answer 7

i dont understand with the random numbers sorry... I know I have to distribute the \[-7x^2y^2\] to all the numbers in the parentheses.. for the first one i got

Answer 8

yes, you multiply it with each term in the parenthesis

Answer 9

\[-42x^4y^2\]

Answer 10

I'm having trouble with the next one

Answer 11

what is -7 * 8 = ?

and y^2 * y = ?

you got x^4 correctly :)

then we'll move to the next part :)

Answer 12

oh I'm meant 56

Answer 13

idk what y^2 * y = ? would be

Answer 14

use the property:
\(\Large a^b \times a^c = a^{b+c}\)

Answer 15

y^3

Answer 16

i need help with the next part

Answer 17

\(-7x^2y^2 (8x^2y -5xy +11xy^2 -31)\)

Now we need to do

-7x^2y^2 * -5xy

what do you get? :)

Answer 18

i dont know.. i need help...i think maybe -35x^3y^3

Answer 19

mhmm, not quite

what is -7 * -5 = ?

negative times negative equals positive :P

Answer 20

35x^3y^3

Answer 21

so far we have

\(-56x^4y^3 + 35x^3y^3\)

we still need to find

-7x^2y^2 * 11xy^2

and

-7x^2y^2 * -31

Answer 22

-77x^3y^4

Answer 23

yes, and

-7x^2y^2 * -31 = ?

Answer 24

217x^2y^2

Answer 25

so our final answer is

\(-56x^4y^3 + 35x^3y^3 -77x^3y^4+ 217x^2y^2\)
