Answer:
Step-by-step explanation:
1. The polynomial must have the following zeros:
2. This means the following:
3. Multiply each term. The product of the multiplicaction is equal to zero. Then:
4. 
and 
are conjugates, therefore, you have:
5. Apply the Distributive property. Then, you obtain:
6. The polynomial of degree 4 and zeros −4, 0, 4 and 6 is:
1) acceleration
2) speed
3) velocity
If u= (u1,u2,u3) andv= (v1,v2,v3), then the dot product of u and v is u·v=u1v1+u2v2+u3v3. For instance, the dot product of u=i−2j−3kandv= 2j−kisu·v= 1·0 + (−2)·2 + (−3)(−1) =−1.
Properties of the Dot Product.
Let u,v, and w be three vectors and let c be a real number. Then u·v=v·u,(u+v)·w=u·w+v·w,(cu)·v=c(u·v).
Further, u·u=|u|2.
Thus, if u=0is the zerovector, then u·u= 0, and otherwise u·u>0.1
Orthogonality Two vectors u and v are said to be orthogonal(perpendicular), if the angle between them is 90◦.Theorem. Two vectors u and v are orthogonal if and only if u·v= 0.
