Question

equação do segundo grau 
3x2-7x+2=0

Answer 1

$3x^{2}-7x+2=0= \Delta= b^{2} -4.a.c= \Delta= -7^{2} -4.3.2= \Delta=49-24=25  x^{1} =-+(-7) \sqrt{25} /2.3=7-5/6=2/6 simplificando 1/3  x^{2} =-+(-7) \sqrt{25} /2.3=7+5/6=12/6=2$


S{1/3,2}

Answer 2

$3x^2-7x+2=0 \\ \\ \Delta=(-7)^2-4.3.2=49-24=25 \\ \\ x=\frac{7+-\sqrt{25}}{2.3}=\frac{7+-5}{6} \\ \\ x_1=\frac{1}{3} \\ \\ x_2=\frac{12}{6}=2 \\ \\ S=\{\frac{1}{3}; \ 2 \}$
