P(x) = x² - 4x - 4
G(x) = x - 2 = 0
G(x) ⇒ x = 2
x² - 4x - 4
⇒ 2² - 4*2 - 4
⇒ 4 - 8 - 4
⇒ - 8

Answer:
x = − 2
Explanation:
We have: x2 + 4 x + 4 = 0
Let's factorise this equation using the middle-term break:
⇒ x 2 +2 x + 2 x + 4 = 0
⇒
x
(
x
+
2
)
+
2
(
x
+
2
)
=
0
⇒
(
x
+
2
)
(
x
+
2
)
=
0
⇒
(
x
+
2
)
2
=
0
⇒
x
+
2
=
0
⇒
x
=
−
2
Therefore, the solution to the equation is
x
= − 2 .
