Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
3x + 5(x - 6) = 3(x + 5) - 5
3x + 5x - 30 = 3x + 15 - 5
3x + 5x - 3x = 15 - 5 + 30
5x = 40
x = 8
Polar form of a complex number is r( cos(theta) + i sin(theta) )
r is equal to the total distance created by the rectangular coordinates of the complex number
r = Root(4^2 + (-4)^2) = Root(32) = 4 Root(2)
To find theta, if a > 0, use arctan(b/a), where:
a = the first number
b = the second number
arctan (-4/4) = -45 degrees (-0.7854 radians)
Your answer is 4 Root(2) (cos(-45) + i sin(-45))

(x-2) is a factor since remainder is 0.
Step-by-step explanation:
We divide (x-2) into the polynomial through long division or synthetic. We choose long division and look for what will multiply with (x-2) to make the polynomial .
We subtract this from the original .
This leaves . We repeat the step above.
.
We subtract this from . We repeat the step above.
.
We subtract this from . We repeat the step above.
.
We subtract this from . There is no remainder. This means (x-2) is a factor.
