Question

a resposta do x2-10x+24=0

Answer 1

x^2-10x+24=0
delta=b^2-4.a.c
delta=(-10)^2-4.1.24
delta=100-96
delta=4
x=-b-/+ raiz de delta / 2a
x=-(-10)-2/2.1
x=10-2/2
x=8/2
x=4
x=-(-10)+2/2.1
x=10+2/2
x=12/2
x=6

Answer 2

x²-10x+24=0
a=1
b=-10
c=24
Δ= -10²-4.1.24
Δ= 100-96
Δ=4
x= -(-10)+- √4
          2.1
x= 10+-2
       2
x'= 6
x''=4
