Answer: The values are a = -4, b = 5 and c = -2.

Step-by-step explanation: We are given to find the values of a, b and c in the following quadratic equation :

$0=5x-4x^2-2\\\\\Rightarrow -4x^2+5x-2=0~~~~~~~~~~~~~~~~~~~~~~~(i)$

We know that

a general quadratic equation is of the following form :

$ax^2+bx+c=0,~a\\eq 0,$

where a is the coefficient of x², b is the coefficient of x and c is the constant term.

Comparing the general equation with equation (i), we get

coefficient of x², a = -4,

coefficient of x, b = 5

and

the constant term, c = -2.

Thus, the values are a = -4, b = 5 and c = -2.
