Question

I WILL FAN AND MEDAL!

Answer 1

Find the product of (x − 5)2.

x2 + 10x + 25

x2 − 10x + 25

x2 − 25

x2 + 25

Answer 2

\[(x − 5)^2\]

\[(x − 5)(x − 5)\]

Answer 3

FOIL

Answer 4

What is foil?

Answer 5

\[(x-a)^2 = x^2 - 2ax + a^2\]

Answer 6

Where are the a's coming from? :(

Answer 8

c and d

Answer 9

Good.
Eliminate: C & D

Answer 10

So do you think its A or B?

Answer 11

I thinks its b

Answer 12

\[ (x − 5)^2 \]
\[ (x − 5) (x − 5)\]

x * x = x^2
x * -5 = -5x

-5 * x = -5x
-5 * -5 = +25

\[ (x − 5)^2 = (x − 5) (x − 5) = x^2 - 10x + 25\]

Answer 13

Oooh That makes a lot more sense thanks for explaining it to me!

Answer 14

Yup B

\[ (x − 5)^2 \]
\[(x − 5) (x − 5) \]
\[ x^2 - 10x + 25\]
