Complex zeros exist in conjugate pairs so the fourth zero is 5 - 4i
So we have
P(x) = ( x - 3)(x + 13)(x - (5 + 4i))(x - (5 - 4i))
= (x - 3)(x + 13)( x - 5 - 4i)(x - 5 + 4i)
= (x^2 + 10x - 39)(x^2 - 5x + 4ix - 5x + 25 -20i - 4ix + 20i -16i^2)
= (x^2 + 10x - 39)(x^2 - 10x + 41)
= x^4 - 10x^3 + 41x^2 + 10x^3 - 100x^2 + 410x - 39x^2 + 390x - 1599
= x^4 - 98x^2 + 800x - 1599 Answer
Answer:
The Answer Shown would be the example!
Step-by-step explanation:
Two plants are being cut by a third plane
Answer:
71°
Step-by-step explanation:
BDH is a triangle (as seen on figure)
<BDH + <DBH = <DHE ( Sum of two interior angles of a triangle is equal to the opposite exterior angle)
40° + 31° = X
X = 71°
Find a number to will divide into both the numerator and denominator equally.
For example, take a look at this fraction: 10/15
What number can both divide evenly into the numerator and denominator? Well, 5!
10/15 / 5/5 = 2/3
.600 + .030 + .002 is another form for that number - this is standard form : )
