for my working, 4(x^2-2x+1) + (x-1) +9

#

I expanded the + (x-1) to x + 1

#

is that wrong?

ruby pawn
#

4(x^2-2x+1) + (x-1) +9 <- This seems correct. Simplify this.

final sequoia
#

someone else expanded to x - 1 which gave them 4x^2 - 7x + 12 when I got + 14 instead

How?

#

What is (4x1)-1+9 ?

#

12 right?

final sequoia
#

yes

ruby pawn
#

4x^2 - 7x +12

final sequoia
#

I think it's because I expanded the (x-1) to x+1

#

wait so where does the brackets go for that then

ruby pawn
#

What do you mean when you say expanded the (x-1) to x+1?

final sequoia
#

ohh

#

I thought + x -1 made it positive for some reason

#

but it stays negative

ruby pawn
#

Which class is this?

final sequoia
#

functions

ruby pawn
#

I mean, is this Calc1?

final sequoia
#

methods of mathematics

#

I think this is touching on pre calc

ruby pawn
#

I see

#

Just try to solve in orders then you should be fine.

final sequoia
#

thank you

ruby pawn
#

Have a good one!

final sequoia
#

thanks you too!
