Explanation:
Given:
x
2
+
10
x
+
16
=
0
To complete the square put the two
x
terms on the left and the constant on the right of the equation:
x
2
+
10
x
=
−
16
Complete the square by multiplying the
x
-term by
1
2
:
1
2
⋅
10
=
5
and adding the square of this number to the right side of the equation:
5

=
25
(

)

=

UNDERSTANDING CHECK:
(

.
The
+
25
was not in the original equation. If we add
+
25
to one side of the equation, we must add the same amount to the other side of the equation to keep it balanced.
(
x
+

)

=

To solve, square root both sides of the equation:

A quadrilateral has 4 sides and 4 angle.
The sum of the 4 angles need to equal 360 degrees.
4th angle = 360 - 25-40-90
4th angle = 205 degrees.
