Resposta:Segue as contas abaixo na explicação é S(3,-1/2)
Explicação passo-a-passo: (4, 4x, 10x+6).
a3/a2=a2/a1
(10x+6)/4x=4x/4
4x.4x=4.(10x+6)
16x²=40x+24
16x²-40x-24=0
Δ=b²-4.a.c
Δ=(-40)²-4.16.(-24)
Δ=1600+1536
Δ=3136
x=-b ± √Δ/2.a
x=-(-40) ± √3136/2.16
x=40 ± 56/32
x1=40+56/32
x1=96/32
x1=3
x2=40-56/32
x2=-16/32:16/16
x2=-1/2
S(3,-1/2)
X1=3--->(4,4.3,10.3+6) x2=-1/2-->(4,4.(-1/2),10.(-1/2)+6)
(4,12,30+6) (4,-4/2,-10/2+6)
(4,12,36) (4,-2,-5+6)
q=3 (4,-2,1)
q=-1/2
