Move the -2x^2 over to the other side to make it positive and then rewrite in descending order of x's. Like this: 2x^2 - 12X + 18. Factor out a 2 to make things easier: 2(x^2 - 6x + 9). Now factor what's inside the parenthesis. Both signs are the same and they're both negative: (x - )(x - ). It's up to us now to find out what goes inside there with those x's. What adds up to -6 has to multiply to +9. Two 3's fit inside there perfectly: -3-3=-6, and -3*-3=9, so the factors are (x-3)(x-3), and setting those equal to zero according to the Zero Product Property, x-3=0 so x = 3 with a multiplicity of 2.
y = 3 x equation represents a proportional relationship.
Answer: Option B
<u>Step-by-step explanation:</u>
A proportional variation represents a relationship between two variables x and y. It can be expressed in the form y=k x. Here, the ‘k’, the proportionality constant is equal to the slope m and the line goes through the origin
case A) 
A linear equation that not passes through the origin and so not proportional variation
case B) y= 3 x
Is a linear equation but passes through the origin and so proportional variation
case C) y = - 3x+2
A linear equation that not passes through the origin and so not proportional variation
case D) 
An inverse variation equation but not passes through the origin and so not proportional variation.
From these, equation option B is the proportion equation because in these equations, there is no addition and subtraction of any constant number. That’s why both these equations become proportional equations.
