RESPONDA COM A FORMULA DE BHASKÀRA

a)a=1 b=0 c= -9

b)a=1 b=0 c= -16

c)a=1 b= -2 c=50

d)a=3 b=1 c= -2

e)a=1 b= -13 c=0

f)a=1 b= -15 c=0

Answer 1

*A*= Não exata !

∆= b²-4ac
∆= (0)²-4(1)(9)
∆= 0-36
∆=-36


*B*= x'=16 e x"= -16

∆=(0)²-4(1)(-16)
∆= 0+64
∆= 64

x=-b±√∆/2a
×= -(0) ± 8 / 2


x'= 8/2 = 16
x"= -8/2 = -16


*C* = x'= 4 e x" = -2

∆= (-2)² -4ac
∆= 4-4 (1)(-2)
∆=4+8
∆=12

x=-(-2)±6 /2

x'= 8/2= 4
x"= -4/2 = -2

*D*= x'= 0 e x"= 13/3

*E*= x' = 13 x"= 0


x= -(-13)±✓(-13)²-4ac /2(1)
x'= 13±13/2 =13

x"= 13-13/2 = 0

*F"= x'=15 e x"= 0

x=-(-15)±√(-15)²-4(1)(0)/2(1)

x=15±15/2

x'=15+15/2 =15
x"=15-15/2=0



É isso.
