Given that the roots of the equation x^2-6x+c=0 are 3+8i and 3-8i, the value of c can be obtained as follows;
taking x=3+8i and substituting it in our equation we get:
(3+8i)^2-6(3+8i)+c=0
-55+48i-18-48i+c=0
collecting the like terms we get:
-55-18+48i-48i+c=0
-73+c=0
c=73
the answer is c=73

Answer:
x = 0, x = 0.5 or 1/2 The points on the graph are ( -1/2 or -0.5,0 ) and ( 1,0 )
Step-by-step explanation:
2x^2-x-1 = -1
2x^2-x = 0
x(2x-1) = 0
x=0
x=0.5 or 1/2
You divide $4.55 by 7.
$0.65 times 9 = $5.85
