Answer:
There are 2 complex roots:
3 - 4i, 3 + 4i.
Step-by-step explanation:
x^2 - 6x + 25 = 0
Using the quadratic formula:
x = [-(-6) ± √(-6)^2 - 4*1*25)] / 2
= (6 ± √-64)/2
= 3 ± 8i/2
= 3 ± 4i

Answer:
x= 4, -7
Step-by-step explanation:
x^2+3x-28
x^2 multipled by -28 = -28
Which two numbers add up to 3 and multiply to -28?
-4 and 7
-4 + 7 = 3
-4 x 7 = -28
so
(x−4)(x+7)=0
4-4=0
-7+7=0
Answer:
Answer: 8PM and 8AM
Step-by-step explanation:
2 |x-2| -12 = 0
2 |x-2| = 12
|x-2| = 6
x-2 = 6
x= 8
12 noon + 8 Hrs
= 8PM
x-2 = -6
x = -4
12 noon - 4 hrs
= 8AM
