What are the values of a, b, and c in the quadratic equation –2x2 + 4x – 3 = 0? a. a = 2, b = 4, c = 3 b. a = 2, b = 4, c = –3 c. a = –2, b = 4, c = 3 d. a = –2, b = 4, c = – 3

we know that

The formula to solve a quadratic equation of the form is equal to

in this problem we have

so

therefore

the answer is the option D

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
