Answer:
2,13×10^-3
213×1/10^3; express to positive product
213/10^3; calculate
213/1000; evaluate
=0.213
2x²-2x-12=0
simplify it into x²-x-6=0
factored form: (x-3)(x+2)=0
solutions: x-3=0 or x+2=0
x=3 or x=-2
Not sure how to explain "what the solutions mean for the equation". One thing you can say is that the solutions mean the equations have two roots/two zeros: 3 and -2, or the graph of 2x²-2x-12 intersects the x axis at (3,0) and (-2,0).
x is called the domain of the problem.
I hope this helps.

I think 2... but I’m sorry if that’s wrong
