2x+3 (x-3) = x+3
Find the value of x


I'm normally good with these


2x+3x-9=x+3
5x-9=x+3
4x-9=3
4x=12
x=3.

Not that hard...

2x + 3 = (x +3)/(x - 3)
2x + 3 = -1
2x = 2
x = 1

2x+3 (x-3) = x+3
Find the value of x


Multiply out the bracket
2x + 3x -9 = x +3
get x's and numbers together
4x = 12
divide by 4 to get the value of x
x=3

2x+3 (x-3) = x+3
= 2x + 3x -9 = x + 3
= 5x -9 = x + 3
= -9 = -4x + 3
= -12 = -4X
= x = 3

since when that 2x + 3 (x-3) its 5x-9????
its 2xsquare - 6x + 3x - 9!

I've got to prove that angle alpha and beta together are 180* - angle ceta, wich is angle delta... And that's the easy part. I've then got to prove that Z-angles are the same...

And after that chapter were going to do some f'(x) ****.

its harder than it looks, because the bracket multiplies out to a quadratic, so there are two answers. needless to say, i'm not doing it.
EDIT: i'm wrong.
Hahahahahahahahahah hahahaha har har har

2x+3(x-3) = x+3

5x-9 = x+3

5x = x+12

4x = 12

x = 3


Easy.


There's no quadratics here either, its 2x + 3 ( x - 3) , not (2x + 3) ( x - 3 )


Quote by Johnny skins

its 2xsquare - 6x + 3x - 9!



No... that would only be correct if the 2x and 3 were in brackets together.

haha.

Still not certain on the answer!

I got

(2x² + 3x) - (6x - 9) = x + 3 as the second step, but I'm pretty sure that's wrong.

EDIT: It's 3. Cheers
