Write the Equation in Standard Order and Identify the Values $2 x^ 2$

Multiple Choice

Write the equation in standard order and identify the values that represent a,b, and c: $2 x^ 2$ =Bx + r²

A) $2 x ^ { 2 } - B x - r ^2 = 0 ; a = 2 , b = - B , c = - r ^2$
B) $2 x ^ { 2 } - B x - r^ 2 ; a = 2 , b = B , c = - r ^2$
C) $2 x ^ { 2 } - B x - r ^2 = 0 ; a = 2 , b = 1 , c = - r ^2$
D) $2 x ^ { 2 } - B x - r^ 2 = 0 ; a = 2 x 2 , b = B x , c = - r^ 2$
