Answer 1

5x² + x + 3 = 0

a = 5

b = 1

c = 3

∆ = b² - 4 . a . c

∆ = 1² - 4 . 5 . 3

∆ = 1 - 60

∆ = - 59

delta negativo não há raízes reais

Answer 2

$\large \boxed{ \begin{array}{l} \rm \: 5x {}^{2} + x + 3 = 0 \\ \\ \Rightarrow \begin{cases} \rm \: a = 5 \\ \rm \: b = 1 \\ \rm \: c = 3\end{cases} \\ \\ \rm\Delta = b {}^{2} - 4ac \\ \Delta = 1 {}^{2} - 4 \: . \: 5 \: . \: 3 \\ \Delta = 1 - 60 \\\Delta = - 59 \leftarrow \Delta < 0 \: \rm \:n \tilde{a}o \: h\acute{a} \: raizes \: reais \end{array}}$
