x-vx=1 (square of x)+3/x=?

Question

We have to find x and then solve the second equasion.

 

Answer 1

x-vx=1

 

Factoring out x we get

 

x(1-v)=1

 

Divide by (1-x) on both sides.

 

x=1/(1-v)

 

We substitute this value of x into  x²+(3/x).  Note that this is an expression and not an equation because expressions to do not contain equal signs.

 

[1/(1-v)]²+[3(1-v)]

 

Simplify the expression.
