Answer:
16
Step-by-step explanation:
You can prove this by taking 16 and dividing it by 2, and you will see that the answer is 8
Hope this helped <3
Answer:
2 Awnsers
Step-by-step explanation:
Because you need one awnser for interior angle sum and one awnser for exterior angle sum. Lmk if you need me to help figure out the 2 sums :)
F(x) = x³ + 3x² - 10x - 24
The root factors must be the factors of 24.
1 x 24 ; 2 x 12 ; 3 x 8 ; 4 x 6.
The most probable roots would be -4, -3, -2, -1, 1, 2, 3, or 4.
Using synthetic division, one can find that the smallest root is -3.
(x - 3)(x² - 6x - 8). The quadratic can now be factored as (x + 2)(x - 4) and further factored as (x - 3)(x + 2)(x - 4).
The correct factors are: (x - 3) (x + 2) (x - 4)
<h3><em>-2x (to the power of 4) + 10x (to the power of 3) - 21x (to the power of 2) +19x -4</em></h3><h3><em /></h3><h3><em>i didn’t know how to type the powers sorry!</em></h3>
The fundamental theorem of algebra states that a polynomial equation of nth degree has n roots (distinct or coincident).
So if one root is already known (5+3i), then there is exact one other root for a total of 2 for a quadratic equation (degree 2).
Furthermore, assuming the coefficients of the quadratic equation are real, then any complex root is accompanied by its complex conjugate, meaning that the sum of the two roots is a real number.
For example, the complex conjugate of 5+3i is 5-3i, because 5+3i + 5-3i = 10, a real number.
So the (only) other root is 5-3i, namely the complex conjugate of the given root.
The graph will be such that it will not touch or cross the x-axis, since the roots are complex.
