Answer:

5 \sqrt{3}i

Step-by-step explanation:

Assuming one root of a polynomial function is

- 5 \sqrt{3} i

Then the other root is

5 \sqrt{3}i

The reason is that , complex roots of polynomial functions occur in pairs.

One complex root is the conjugate of the other.

This means that, if

x -  yi

is a root, then

x  +  yi

is also a root.

If a polynomial has four terms, 3x3 5x 6x2 10, which factoring method can be considered? perfect-square trinomial difference of
Tems11 [23]

The factoring method which can be considered for such a cubic tetranomial expression is; factor by grouping sum of cubes.

<h3>What factoring method can be considered for the polynomial?</h3>

It follows from the task content that the order of the Polynomial is 3 and the polynomial is a tetranomial as it contains 4 terms.

On this note, since 3x³ is not a perfect cube, it follows that the best factorisation method for such a polynomial is; factor by grouping sum of cubes.

Suppose △PKN≅△BGH.
OLga [1]

Answer:

△KNP ≅ △GHB

△NPK ≅ △HBG

Step-by-step explanation:

Given: △PKN≅△BGH

This means two triangles PKN and BGH are congruent. Congruent triangles havecongruent  corresponding parts.

So,

  • PK ≅ BG;
  • PN ≅ BH;
  • KN ≅ GH;

and corresponding vertices

  • P to B;
  • K to G;
  • N to H.

Hence,

A. Triangle KNP is congruent to triangle GHB - true

B. Triangle KPN is congruent to triangle GBH - false

C. Triangle NKP is congruent to triangle HGB - false

D. Triangle NPK is congruent to triangle HBG - true
