Question

3x ao quadrado+5x+2=0

Answer 1

$\LARGE\tt{} {3x}^{2} + 5x + 2 = 0 \\ \LARGE\tt{}a = 3 \\ \LARGE\tt{}b = 5 \\ \LARGE\tt{}c = 2 \\ \\\LARGE\tt{} {b}^{2} - 4 \times \left(a\right) \times \left(c\right) \\ \\ \LARGE\tt{} \Delta = {5}^{2} - 4 \times \left(3\right) \times \left(2\right) \\ \\ \LARGE\tt{}\Delta = 25 - 24 \\ \LARGE\tt{}\Delta = 1$

Então concluímos que: A equação terá dois valores reais distintos
