Answer 1

Respuesta:

:)

Explicación paso a paso:

(x - 3)² = 2(x + 3) - 5

(x)² + 2(x)(-3) + (-3)² = 2x + 6 - 5

x² - 6x + 9 = 2x + 1

x² - 6x - 2x + 9 - 1 = 0

x² - 8x + 8 = 0

a = 1

b = -8

c = 8

{-b ± √[(b)² - 4ac]} / 2a

{-(-8) ± √[(-8)² - 4(1)(8)]} / 2(1)

{8 ± √[64 - 32]} / 2

{8 ± √32} / 2

{8 ± √(2·2·2·2·2)} / 2

{8 ± 4√2} / 2

x1 = {8 + 4√2} / 2

x1 = 4 + 2√2

x2 = {8 - 4√2} / 2

x2 = 4 - 2√2
