Answer:
Real roots: -4, 1
Complex roots: 2-5i, 2+5i
Step-by-step explanation:
(x²+3x-4)(x²-4x+29)
x²+3x-4=x²+4x-x-4=x(x+4)-(x+4)=(x-1)(x+4)
x²-4x+29 does not have real roots, since delta=16-4×29=-100<0.
However it has complex roots:
(4+/-10i)/2=2+/-5i
So the real roots are: -4 and 1
Complex roots: 2-5i, 2+5i

Answer:
<h2>d = -4</h2>
Step-by-step explanation:

4 = -d <em>change the signs</em>
-4 = d ⇒ d = -4
