Answer 4

we love pdf form!

Answer 5

:)

Answer 6

ok your job here is to multiply. in each case you will have to do FOUR multiplications, just like you would if you multiplied two 2-digit numbers

Answer 7

lets start with
\[(x-5)^2\] which means
\[(x-5)(x-5)\]

Answer 8

please don't put
\[(x-5)^2=x^2-25\]or your math teacher will think you are a moron. you have to first write out
\[(x-5)(x-5)\] and then perform FOUR multiplications

Answer 9

like this
\[(x-5)(x-5)=x\times x - x \times 5 - 5 \times x - 5 \times -5\]
\[x^2-5x-5x+25\]
\[x^2-10x+25\]

Answer 10

with a little practice you will see that
\[(x-b)^2=x^2-2bx+b^2\] but at the beginning just multiply out

Answer 11

ok... so I just do the distributive property when multiplying?

Answer 12

first problem
\[(a-b)(a-b)=a\times a -a \times b-b\times a -b \times -b\]
\[a^2-2ab+b^2\]

Answer 13

yes the distributive property. you have it exactly!

Answer 14

make sure to do all FOUR multiplications if it is two terms times two terms. the answer to question one is SOMETIMES

Answer 15

it would be true for example if

\[b=0\]

Answer 16

if you want, try #3 and i will check your answer

Answer 17

Okay... I will.

Answer 18

Okay,
(x+3)^2
(x+3)(x+3)
x^2+x3+x3+9
x^2+6x+9
so option one.
???

Answer 19

ohh, forgot about formatting problems...

Answer 20

yes you have it exactly
