Question

How can I simplify :
y = (x - 3)² - 1
Or is it already simplified?

Answer 1

Apparently I need to combine like terms, but I don't see any :/

Answer 2

y=x^2 - 9 -1
y=x^2 -10
?
i think that is how u do it

Answer 3

Okay so that would be the simplified form?

Answer 4

I just need to know for sure.

Answer 5

yea cuz u need to distribute the exponent

Answer 6

(x-3)^2 is not equal to x^2 - 9

Answer 7

it isnt?
oh i am wrong then

Answer 8

@jim_thompson5910 So what would be the siplified form of this?

Answer 9

Or is it already?

Answer 10

you use the FOIL rule to expand out (x-3)^2 or (x-3)(x-3)

Answer 11

it would be +9

Answer 12

a table like this may help
