Question

y(elevado a 2)-16y+64=0

Answer 1

y^2-16y+64=0
delta=b^2-4ac
delta=(-16)^2-4.1.64
delta=256-256
delta=0
x=-b-/+ raiz de delta/2a
x=-(-16)-0/2.1
x=16-0/2
x=16/2
x=8

Answer 2

y² - 16y + 64 = 0

A= 1

B= - 16

C= 64

∆= b² - 4ac

∆= ( - 16)² - 4 • 1 • 64

∆= 256 - 256

∆= 0

x= - b ± √∆/2a

x= - ( - 16) ± √0/2 • 1

x' e x''= 16 ± 0/2 = 16/2 = 8

S= ( 8 )
