Question

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

Answer 1

Answer:

a = 2, b = 4, c= - 3

Step-by-step explanation:

Given quadratic equation is:

$2 {x}^{2} + 4x - 3 = 0 \\ equating \: it \: with \: the \: general \: form \: \\ of \: quadratic \: equation : \\ a {x}^{2} + bx + c = 0 \\ we \: find \: \\ a = 2, \: \: b = 4, \: \: c = - 3$

Hence, 2nd option is the correct answer.

Answer 2

Answer: D

a = –2, b = 4, c = – 3
