Answer 1

Resposta:

Explicação passo a passo:

2) x² - 36 = 0

x² = 36

x = ±√36

x = ±6

3) 3x² - 48 = 0

3x² = 48

x² = 48/3

x² = 16

x = ±√16

x = ±4

4) 4x² = 0

x² = 0/4

x² = 0

x = ±√0

x = 0

d) x² + 6x = 0

x(x + 6) = 0

x = 0

ou

x + 6 = 0

x = -6

e) 2x² - 4x = 0

2x(x - 4) = 0

2x = 0

x = 0/2

x = 0

ou

x - 4 = 0

x = 4

f) -5x² = 0

x² = 0/(-5)

x² = 0

x = ±√0

x = 0

Answer 2

Resposta:

Explicação passo a passo:

2 - $x^{2}$ = 36

x = ± 6

x' = 6

x'' = -6

3 - $x^{2}$ - 16 = 0

$x^{2}$ = 16

x = ± 4

x' = 4

x'' = -4

4 - 4$x^{2}$ = 0

$x^{2} = 0$

d) $x^{2} + (x + 6) = 0$

x = 0

x + 6 = 0

x = 0

x = - 6

x' = -6

x = 0

e) 2x × (x- 2) = 0

x × (x - 2) = 0

x = 0

x - 2 = 0

x = 0

x = 2

f) $5x^{2} = 0$

$x^{2} = 0$

x = 0
