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

Question

Quizplus · Accepted Answer

The standard form of a quadratic equation is given by:
ax² + bx + c = 0
Comparing the given equation with the standard form, we get:
a = 2, b = -B and c = -r²
Therefore, option A is the correct choice as it represents the equation in standard form and correctly identifies the values of a, b, and c.
