So, 3.55 g of copper could be made from 4 g of copper oxide.
The formula for copper oxide to convert to copper is a chemical equation Cupric oxide, or copper (II) oxide, is an inorganic compound with the chemical formula CuO.
12+49i
when you get i^2 it's the same as multiplying by -1 so
factoring it out will turn out like this
15i^2+40i+9i+27
instead of 15 i^2 multiply 15 x-1
-15+49i+27
12+49i
