5x= x²/2 multiply both sides by 2
10x=x²
x² - 10x=0 factor x
x(x-10)=0
x=0 or x-10=0
x=0 or x=10 the solution
Correction:you only divide by a variable when you are sure it is not equal to zero.
5x= x^2/2
x^2/2-5x=0
x(x/2-5)=0
x= 0 or x/2-5=0, in which case x/2=5, x=5*2=10
so x=0 and x=10 are the two solutions
10x = x²
x² - 10x = 0
x (x - 10) = 0
x = 0 , x = 10
^you cannot divide out a variable. By doing that you are assuming it is non zero and you lose the solution when x=0
5X=X2/2
multiply both sides by two:
10X=X2
divide both sides by X:
X=10
Edit: Whoops, I guess I tried so hard to be the first to answer that I overlooked that detail. My apologies:P
