Question

What are the values of a, b, and c in the quadratic equation 0 = 5x - 4x2 – 2?
a = 5, b = 4, C = 2
O a= 5, b= -4, C = -2
O a=-4, b = 5, c = -2
O a = 4, b = -5, c = -2

Answer 1

Answer:

Option C.

Step-by-step explanation:

The standard form of a quadratic function is

$ax^2+bx+c=0$         ... (i)

The given equation is  

$0=5x-4x^2-2$

It can be rewritten as

$-4x^2+5x-2=0$        ... (ii)

On comparing (i) and (ii), we get

$a=-4,b=5,c=-2$

Hence, the correct option is C.
