Question

Choose the equation that best represents the general form of the following expression. x^2/2 = 7x. - x2 + 14x + 0, x2 + 14x = 0, x2 - 14x = 0, or x2 - 7x + 2 = 0?

Answer 1

The correct answer should be the third option hope this helped  

Answer 2

Cross multiplying we get
x^2 = 2*7x
x^2 = 14x
x^2 - 14x = 0  is the answer
