Answer:

Step-by-step explanation:

A quadratic equation is an equation of the form

a

x

2

+

b

x

+

c

=

0

, where

a

≠

0

.

The form

a

x

2

+

b

x

+

c

=

0

is called the standard form of the quadratic equation.

Notice that standard form is not unique.

For example,

x

2

−

x

+

1

=

0

can be written as the equivalent equation

−

x

2

+

x

−

1

=

0

.

Also,

4

x

2

−

2

x

+

2

=

0

can be written as the equivalent equation

2

x

2

−

x

+

1

=

0

.

In this exercise, all answers are reported in the form

a

x

2

+

b

x

+

c

=

0

with

a

>

0

,

and where the greatest common factor of all nonzero coefficients is 1 .

In this exercise, you will practice writing quadratic equations in standard form.
