Rewrite the polynomial-9x^5+36x^4+189x^3 in factored form, using the factoring method method you prefer.
ozzi

The polynomial 9x^5+36x^4+189x^3 in factored form is -9 x \times x \times x \times(x-7) \times(x+3)

<u>Solution:</u>

Given, polynomial equation is -9 x^{5}+36 x^{4}+189 x^{3}

We have to find the factored form of the above given polynomial equation.

Let us solve it by grouping.

Now, take the polynomial ⇒ -9 x^{5}+36 x^{4}+189 x^{3}

By taking common term out, we get

\rightarrow-9 x^{3}\left(x^{2}-4 x-21\right)

\rightarrow-9 x^{3}\left(x^{2}-(7-3) x-7 \times 3\right)

Grouping the terms we get,

\rightarrow-9 x^{3}\left(\left(x^{2}-7 x\right)+(3 x-7 x^3)\right)

Taking common terms out from each group,

\rightarrow-9 x^{3}(x(x-7)+3(x-7))

\Rightarrow-9 x^{3}((x-7)(x+3))

\rightarrow-9 x \times x \times x \times(x-7) \times(x+3)

Thus the factored form of polynomial is found out

Line segment Z E is the angle bisector of AngleYEX and the perpendicular bisector of Line segment G F. Line segment G X is the a
Vinil7 [7]

The correct option that depicts the centroid of the triangle is; C. Point A is the center of the circle that passes that passes through the points E, F and G and is the center of the circle that passes through the points X, Y and Z.

<h3>How to interpret the segments formed from Triangle Centroid?</h3>

The center of inscribed circle into the triangle is the point where the angle bisectors of the triangle meet.

The center of the circumscribed circle over the triangle is the point where the perpendicular bisectors of the sides meet.

Line segments ZE, FY and GX are both angle bisectors and perpendicular bisectors of the sides. Thus, the point of intersection of line segments ZE, FY and GX is the center of inscribed circle into the triangle and the center of the circumscribed circle over the triangle.

Inscribed circle passes through the points X, Y and Z. Circumscribed circle passes through the points E, F and G. So, point A is the center of the circle that passes that passes through the points E, F and G and is the center of the circle that passes through the points X, Y and Z.

Thus, the correct option is option C. Point A is the center of the circle that passes that passes through the points E, F and G and is the center of the circle that passes through the points X, Y and Z.

Each column of the matrix represents a vertex of a triangle. If Rosa scales the triangle by finding 3T, what are the vertices of
Ainat [17]

Answer:

(0,0), (0,9), (9,0)

Step-by-step explanation:

The matrix corresponding vertices are:

(0,0)

(0,3)

(3,0)

Rosa scales by 3T, so we need to multiply each point by 3.

(3*0, 3*0)

(0*3, 3*3)

(3*3, 0*3)

=

(0,0)

(0,9)

(9,0)
