Someone help with question a,c,e and g pls with working out , it’s urgent. I’ll mark brainliest

A,C and G are not quadratic equations where as E is a quadratic equation.(Though C could be a quadratic equation).

C could be a quadratic equation if you transpose 5 to LHS.

A is not a proper equation because x is not present in it and G is not a quadratic equation but it's linear equation.

Hope it helps you.
