Answer:
-30\/10
Step-by-step explanation:
So you want to start to factor so you get (x²+2)(x²-7) = 0. Now set each () to 0, so you get (x²+2) = 0 and (x²-7)=0. The first ends with +√2i and -√2i, the second ends with +√7 and -√7
This is called a double equation. If you solve for X, you would get 'any whole number.'
