Step  1  :

 Raise  x to the  2nd power
Exponentiaion :

Equation at the end of step  1  :

  y -  ((2 • x2) +  3)  = 0 
Step  2  :

Simplify   y  -  2x2+3
Trying to factor a multi variable polynomial :

 2.1    Factoring    y - 2x2 - 3 

Try to factor this multi-variable trinomial using trial and error 

 Factorization fails

Equation at the end of step  2  :

  y - 2x2 - 3  = 0 
Step  3  :

Solve   y-2x2-3  = 0 
Solving a Single Variable Equation :

 3.1     Solve   y-2x2-3  = 0

thanks! but the only problem is my problem is a negative 2, and this one seems like it isn't?

parentheses, they are important

you don't need to solve anything, they just want you to plug and chug

So what do you get for y if you let x=-3?
