Question

Equação do 2° Grau: 3x²-7x+2=0

Answer 1

3x^2-7x+2
delta=b^2-4ac
delta=(-7)^2-4*3*2
delta=49-24
delta=25
x1=-b+raiz de delta/2*a
x1=-(-7)+5/2*3= 7+5/6 = 12/6=2

x2=-(-7)-5/2*3= 7-5/6=  2/6

Answer 2

solução 2,⅓
$3x ^{2} - 7x + 2 = 0$
∆=(-7*2)-4.3.2
∆=49-24 ∆=25
x=-(-7)±√25
2.3
x=-(-7)±5
