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

a = 5, b = 4, c = 2
a = 5, b = –4, c = –2
a = –4, b = 5, c = –2
a = 4, b = –5, c = –2

Answer :

We need to find the values of a, b, and c in the quadratic equation

The general form of quadratic equation is

First we arrange the equation in order. x^2 should come first

can be written as

The coefficient of x^2 is the value of 'a' = -4

The coefficient of x is the value of 'b' = 5

The constant is the value of 'c' = -2

So a = -4, b=5 and c= -2

correct answers below:

step-by-step explanation:

given that ab is divided into equal parts as

ac, cd, de, ef, fg, gh, hi, ib.

from this we find that f is the midpoint of ab.

so using mid point formula we find

f = (3,7)

similarly considering fb, we get

h = mid point of fb = ((6,6) and g, mid point of fh is

g = (9/2, 13/2)

i is mid point of hb

so i =(15/2,11/2)
