Question

4x ao quadrado -7x+3=0

Answer 1

$4x^2-7x+3=0$

a=4, b=-7 c=3

Fórmula de Bhaskara, anexa

$delta = (-7)^2-4.4.3 = 49-48 = 1 \\ \\ \sqrt{delta} = \sqrt{1} = 1 \\ \\ x_{1} = \frac{-(-7)+1}{2.4} = \frac{8}{8} =1 \\ \\ x_{2} = \frac{-(-7)-1}{2.4} = \frac{6}{8} = \frac{3}{4}$

S{1,$\frac{3}{4}$}
