Question

how to solve x2-(4x+4) by (x-2)

Answer 1

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 2

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

⇒
