Question

1. Resolva a equação incompleta. a)16y²-9=0

Answer 1

16y² - 9 = 0

16y² = 9

y² = 9/16

y = ± √9/16

y = ± 3/4

Answer 2

Resposta:

x = -b±√b²-4ac

-------------------

2 a

x = - ( 0 ) ± √ 0² - 4 (16)(-9)

-----------------------------------------

2 (16)

x = 0 ± √ 0 + 576

-----------------------

32

x = ±24/32

x = ± 3/4
