6) Relacione *
(x + 3) (x + 3) (x – 2) (x – 2) (x – 4)2 (x + 3) (x – 3)
a) x2 + 6x + 9
b) x2 – 8x + 16
c) x2 – 9
d) x2 - 4x + 4
a) x2 + 6x + 9
b) x2 – 8x + 16
c) x2 – 9
d) x2 - 4x + 4

Answer 1

(x + 3) (x + 3)

x² + 3x + 3x + 9

x² + 6x + 9 (A)

(x - 2) (x - 2)

x² - 2x - 2x + 4

x² - 4x + 4 (D)

(x - 4)²

x² - 2 . x . 4 + 4²

x² - 8x + 16 (B)

(x+3) (x-3)

x² - 3x + 3x - 9

x² - 9 (C)
