Step-by-step explanation:
Substitute a = - 6 into the expression, that is
a² + 7a + 8
= (- 6)² + 7(- 6) + 8 = 36 - 42 + 8 = - 6 + 8 = 2
<em>For another information, when D > 0, there are 2 real roots.</em>
<em>When D = 0, there is only one real root.</em>
<em>And when D < 0, there are no real roots (also known as imaginary.)</em>
