Answer:

=x⁴−x³−14x²

Step-by-step explanation:

<h3>Let's simplify step-by-step.</h3>

x²(3x²+5x−4)−2x²(x²+3x+5)

<h3>Distribute:</h3>

=(x²)(3x²)+(x²)(5x)+(x²)(−4)+−2x⁴+−6x³+−10x²

=3x⁴+5x³+−4x²+−2x⁴+−6x³+−10x²

<h3>Combine Like Terms:</h3>

=3x⁴+5x³+−4x²+−2x⁴+−6x³+−10x²

=(3x⁴+−2x⁴)+(5x³+−6x³)+(−4x²+−10x²)

=x⁴+−x³+−14x²

<h3>ANS-</h3>

=x⁴−x³−14x²

Because of the unique line postulate, we can draw unique line segment PM. Using the definition of reflection, PM can be reflecte
Karolina [17]

By the definition of reflection, point P is the image of itself and point N is the image of<u> Point M. </u>

<u></u>

<h2 /><h2>Given that</h2>

Because of the unique line postulate, we can draw a unique line segment PM.

Using the definition of reflection, PM can be reflected over line l.

By the definition of reflection, point P is the image of itself and point N is the image of ________.

Because reflections preserve length, PM = PN. Point M point Q segment PM segment QM.

<h3></h3><h3>According to the question</h3>

P is a point on the perpendicular bisector, l, of MN.

A Reflection is a transformation in which the figure is the mirror image of the other.

Every point is a mirror reflection of itself.

By the definition of reflection, point P is the image of itself, point N is the image of M.

Line l acts as a Line of symmetry or axis of reflection.

Reflections preserve length so PM = PN.

By the definition of reflection, point P is the image of itself and point N is the image of<u> Point M. </u>

Because reflections preserve length, PM = PN.

Point M point Q segment PM segment QM.

Hence, point N is the image of M.
