Question

Encontre a raiz real da equação 3x²-7x+4=0

Answer 1

3x² - 7x + 4 = 0
Delta = (-7)² - 4*(3)*(4)
Delta = 49 - 48
Delta = 1
X = 7/6 +- 1/6
x' = 8/6 = 4/3
x" = 6/6 = 1

Answer 2

Resposta:

3×*2-7× +4 = 0

delta=(-7)*2-4(3)*(4)

delta= 49-48

delta= 1

X= 7/6+ -1/6

x ' 8/6= 4/3

x ' =6/6= 1
