Question

if i factor something out of something squared, does the thing i factor out become squared?

Answer 1

example: ( x + x.5 + x)^2 = x(1 + 1.5 + 1)

Answer 2

wrong, wait

Answer 3

\[\sqrt{4x - 4y} = 2\sqrt{x-y}\]

Answer 4

( x + x.5 + x)^2 = x(1 + 1.5 + 1)^2

Answer 5

could you use my example?

Answer 6

Ohhhh. I don't think mine helped.

Answer 7

so my question is: ( x + x.5 + x)^2 = x(1 + 1.5 + 1)^2 or = x^2(1 + 1.5 + 1)^2

Answer 8

i'm 99% sure it's the first one

Answer 9

Is that 0.5x? like x/2?

Answer 10

i'll write it again for you

Answer 11

( x + x*5 + x)^2 = x(1 + 1*5 + 1)^2 or = x^2(1 + 1*5 + 1)^2

Answer 12

im sure it's x(1 + 1*5 + 1)^2, so i'm just double checking

Answer 13

I think it's x^2(1+5+1)^2. If you were to expand it all terms have x^2 in it.

Answer 14

Also, (x+5x+x)^2 = (7x)^2

Answer 15

So, 49x^2

Answer 16

so it's x^2(1 + 1*5 + 1)^2 ?

Answer 17

Yeah. The more I think about it, it seems to get more clear.

x^2(1+5+1)^2 = (x+5x+x)^2 = 49x^2

Answer 18

i see

Answer 19

Yeah. Just try (x+5x+x)(x+5x+x), it's not hard to expand out. Thats what I did to make sure I was telling you the right thing :)

Answer 21

alright, thanks for clearing that up
