Plss me also this how to answer this a quadratic equation there is 4 categories to put some answer standard forms and a set of a b and c me guys i need an answer before june 30 2019‍♀️‍♀️

see explanation

Step-by-step explanation:

The standard form of a quadratic equation is

ax² + bx + c = 0 : a ≠ 0

Express the equations in this form and extract the coefficients

1

4 - 2x + 3x² = 0 , that is

3x² - 2x + 4 = 0 ← in standard form

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

2

x(x + 5) - 2x = 0 ← distribute parenthesis

x² + 5x - 2x = 0

x² + 3x = 0 ← in standard form

with a = 1, b = 3 and c = 0

3

x² - 2x(x - 2) + 5 = 0 ← distribute parenthesis and simplify

x² - 2x² + 4x + 5 = 0

- x² + 4x + 5 = 0 ← in standard form

with a = - 1, b = 4 and c = 5

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

that is the sum

there are no other answers without knowing the variables values
