Question

Resposta para 3x²-10x+3=0

Answer 1

formula de baskara     vou chamar delta de Q
b^2-4.a.c
10^2-4.3.3
100-36
DELTA=64---->8

x´=-b+Q/2.a
x'=10+8/2.3------->18/6=3

x''=10-8/2.3--------->2/6=1/3

Answer 2

3x² - 10x +3=0          dados: a=3, b=-10, c=3

Δ = b²-4.a.c
Δ = (-10)² - 4.3.3
Δ = 100 - 36
Δ = 64

considerando d=Δ

$x = \frac{-b+- \sqrt{d} }{2.a} \\ \\ x' = \frac{-(-10)+ \sqrt{64} }{2.3} \\ x' = \frac{10+8}{6} \\ x'= \frac{18}{6} \\ x' = 3 \\ \\ x"= \frac{-(-10)- \sqrt{64} }{2.3} \\ x"= \frac{10-8}{6} \\ x"= \frac{2}{6} \\ x"= \frac{1}{3}$

Espero ter ajudado... Bons estudos!!
