The quadratic equation is about the polynomial equation in the single variable where the highest exponent of a variable is only 2. If you want to know solving quadratic equations, you will have three main ways to solve the quadratic equation.

1. Methods of Solving
Quadratic Equations

3. The first one is to factor the quadratic equation when
you are able to do this, you can also use the quadratic
formula or you can complete the square. If you want to
use any of these methods, you have to be aware of the
step by step to follow .

4. Factoring of the quadratic
equation
• Combine the like
terms and move them
at just one side: you
should start by
factoring the equation
by moving all the
terms to go to one
side of an equation
and to keep the
square root positive.

5. In combining the
term, then you
should subtract or
add the terms that
are a square root,
that have variable
terms and these of
constant. If the
side does not have
the remaining term,
you may write 0
and the other side
of the equal sign.

6. •Factoring of
expression: if you
want to factor
expression, you
will have to use the
factors term and
the factors of the
constant term in
order to multiply
them and to add
up the middle
terms.

7. You can then set every
set in the parenthesis
which equal to zero into
the separate equation.
This can lead in finding
out the two values, and it
can make an entire
equation to be equal to
zero. When you have
finished factoring the
equation, then you may
put all the expression on
every set of the
parenthesis that equal to
zero.

9. When you have finished
factoring the equation,
then you may put all the
expression on every set
of the parenthesis that
equal to zero. To get
the multiplication of
zero, there are rules,
principles, and rules.
This means that if any
of the factors outside of
the parentheses equal
to zero, the one outside
may also equal to zero.

10. •You can then solve each zeroed equation alone. In the
quadratic equation, they can be two values for the x. You
can find x for every possible value and one by one
through isolating variables and writing down two
variables for two solutions of the x like the final solution.

11. The use of Quadratic
Formula
• You should start
by combining the
likes term and to
move them from
one side to
another. You can
move the terms
from one side of
an equal sign
and to keep the
square root term
positive.

13. When you are
writing the
terms, you
should use the
descending
order for the
degree and the
term will come
first and them
the variable
term and the
rest is the
constant term.

14. •After writing
down the
formula, you
should
identify the
value of the
quadratic
equation and
fill them into
the formula.

15. Calculate: after
plugging in
numbers, you can
do remaining math
in order to simply
the negative and
the positive sign, to
multiply and to get
the square of the
remaining terms.

16. You can then simplify
the square root.
When the number in
the radical symbol is
not that perfect, you
can get the whole
number. When the
number does not
have a perfect
square, you will have
to simplify it to reach
to the simplest
radical version.

17. The third option is completing a
square root
• You can start by
moving all the terms at
one side of the
equation and ensure
that the square root is
positive before putting
the constant to its side
and to continue with
the procedure.
