sebd me some questions about anything ill solve for yall
how to solve x²=2x+8 factorization?
x=2x+8
x2x=2x+82x
x2x=8
x=8
x/1=8/1
x=8
prove:
if x=8
8=2(8)+8
8=16+8
8=8
(PROVEN)
Manifoldee
×=2x8 minus both sides by 2x
Manifoldee
so, x2x=2x+82x
Manifoldee
then cancel out 2x and 2x, cuz 2x2x is obviously zero
Manifoldee
so it would be like this: x2x=8
Manifoldee
then we all know that beside the variable is a number (1): (1)x2x=8
Manifoldee
so we will going to minus that 12=1
Manifoldee
so it would be x=8
Manifoldee
so next step is to cancel out negative number beside x so we get positive x
Manifoldee
so by doing it you need to divide both side by 1 so it would be like this: (1x/1)=(8/1)
Manifoldee
SO THE ANSWER IS X=8
Manifoldee
so we should prove it
Manifoldee
x=2x+8
x2x=8
x=8
x=8 by mantu from India
mantu
lol i just saw its x²
Manifoldee
x²=2x8
x²2x=8
x²=8
x²=8
square root(x²)=square root(8)
x=sq. root(8)
Manifoldee
I mean x²=2x+8 by factorization method
Kristof
I think x=2 or x=4
Kristof
x= 2x+8
×=82x
 2x + x = 8
 x = 8 both sides divided  1
×/1 = 8/1
× =  8 //// from somalia

mantu
what's the formula
Modress
deals with circles, angles, and triangles. Usually in the form of Soh cah toa or sine, cosine, and tangent
Thomas
solve for me this equational y=2x
what are you solving for
Alex
you would move everything to the other side leaving x by itself. subtract 2 and divide 1.
Nikki
goodness. I'm sorry. I will let Alex take the wheel.
Nikki
I think he drive me safe
