Question

Raiz da formula de bhaskara
x2+8x+6=0

Answer 1

a=1
b=8
c=6
Na fórmula de delta: b²-4.a.c
Δ=8²-4.1.8

Δ=64-24

Δ=40

Na fórmula de Bhaskara $\frac{-b+- \sqrt{delta} }{2.a}$

$\frac{-8+- \sqrt{40} }{2.1}$

x1= $\frac{-8+2 \sqrt{10} }{2}$

x2=$\frac{-8-2 \sqrt{10} }{2}$


x1= -1+√10 e x2= -1-√10
Espero ter ajudado

Answer 2

-8 ±√8² - 4(1)(6)
