Question

x²+10x+24=0 alguém ajuda

Answer 1

Δ = b² - 4 . a . c
Δ = 10² - 4 . 1 . 24
Δ = 100 - 96
Δ = 4

Bháskara:

-b +- √Δ / 2 · a

-10 +- √4 / 2
-10 +- 2 / 2
$\left \{ {{x'=-10+2 /2 = -8 / 2 = -4} \atop {x''=-10-12 /2 = -12 / 2 = -6}} \right.$

Respostas: 
x' = -4
x'' = -6.

Answer 2

Δ=B²-4·A·C
Δ=10²-4·1·24
Δ=100-96
Δ=4

X=-B+-√Δ
          2.A
X=10+-4
         2
X1=10+1=11=5,5
           2     2
X2=10-1=9=4,5
          2    2
