Question

X²-6x+5=0 usando baskara

Answer 1

a=1. b=6. c=5
delta= 36-4×1×5=36-20=16
X=-6+/- 4 ÷2=
x1= -1
x2= -5

Answer 2

a = 1 / b = -6 / c = 5

Δ = b² - 4ac
Δ = -6² - 4x1x5
Δ = 36 - 20
Δ = 16
√16 = 4
-----------------
x = -b +- √Δ / 2a 

x' = - (-6) - √16 / 2x1 => 6-4/2 => 2/2 => 1
x'' = - (-6) + √16 / 2x1 => 6+4/2 => 10/2 => 5

x = {x', x''}
=> x = {1, 5}
