Answer 2

Step-by-step explanation:

${x}^{2} + ax + 4 = 0$

$by \: using \: determinant \: form$

${b}^{2} - 4ac > 0$

$a > 4 \: and \: \: a > - 4$

$x \: belongs \: to \: ( - \infty . - 4)u(4. \infty )$

${a}^{2} - 4(1)(4) > 0$

${a}^{2} - 16 > 0$

$(a - 4)(a + 4) > 0$

x belongs to (-infinity, -4)U(4,infinity)
