Verified answer

x² - 10x + 16 = 0

baskhara

delta

d² = 100 - 64 = 36

d = 6

x1 = (10 + 6)/2 = 8

x2 = (10 - 6)/2 = 2

pronto

x²-10x+16=0

x = -b + ou - (raiz)∆

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

2a

∆ = b² - 4.a.c

∆ = 10² - 4. 1 . 16)

∆ = 100 - 4 .16

∆ = 100-64

∆ = 36

x' = (-b + {raiz}36 ) : 2a

x' = [-(-10) + 6] : 2.1

x' = (10 + 6) : 2

x' = 16 :2

x' = 8

x" = ( -b - {raiz}36 ) :2a

x" = [-(-10) - {raiz}36] :2.1

x" = (10 - 6) : 2

x" = 4 :2

x" = 2
