Yes,it is a quadratic equation.

(A) To determine if the equation $7x = 2x^2$ is quadratic,we rewrite it in the standard form $ax^2 + bx + c = 0$.Rearranging the terms,we get $2x^2 - 7x = 0$.Comparing this with the standard form $ax^2 + bx + c = 0$,we have $a = 2$,$b = -7$,and $c = 0$.Since the highest power of the variable $x$ is $2$ and $a \neq 0$,the given equation is a quadratic equation.
