Identify a, b, and c from the quadratic equation. $$2 x ^ { 2 } = 7 x$$
A) $a = 7 , b = - 2 , c = 0$
B) $a = 2 , b = - 7 , c = 0$
C) $a = 0 , b = 7 , c = 2$
D) $a = 0 , b = 0 , c = 7$
E) $a = 2 , b = 0 , c = 7$

Quizplus · Accepted Answer

The quadratic equation is in the form of $ax^2+bx+c=0$, so we need to rewrite it as $2x^2-7x=0$. From there, we can see that $a=2$, $b=-7$, and $c=0$. Thus, the best choice is $\boxed{	ext{B}}$.
