Answer 1

Hello...Nicky

 

I am not familiar with the box method. So, let me solve it in a different way.

2x^2+3x=9              I am going to subtract 9 from both sides.

         -9    -9

2x^2+3x-9= 0 

(2x-3)(x+3)=0

2x-3= 0             x+3=0

   x= 1.5             x= -3

Again, glad to help a little.  I will look up how to solve it using the box method.
