There are two parts to this problem we need to acknowledge.

First, we need to multiply using the distributive property, or FOIL.

-2x(6x^4 - 7x^2 + x - 5)

Multiply -2x by each term.

<h3>-12x^5 + 14x^3 - 2x^2 + 10x</h3>

Now, fortunately, the expression is already in standard form.

Standard form of a polynomial is where the term of the largest degree is listed first, and as the polynomial continues from left to right, the degree decreases per term.

The highest degree is 5, and the expression is already listed in standard form as the degrees go: 5, 3, 2, 1.

Find a polynomial, which, when added to the polynomial 5x^2–3x–9, is equivalent to <br><br> x^2-5x+6
alexandr1967 [171]
So this is easy counting
so 5x^2-3x-9
we have 5 x^2's
-3 x's
-9

wat do we add to that to get
1 x^2's
-5 x's
+6
so we do each
5x^2+what=1x^2
subtract 5x^2
from both sides
what=-4x^2
first is -4x^2

then we have -3x to -5x
-3x+what=-5x
add 3x to both sides
what=-2x
second is -2x

-9 to 6
-9+ what=6
ad d9
what=15
last is 15
thereffor add -4x^2-2x+15

Answer:   \bold{\dfrac{27x^2y^3}{16}}

<u>Step-by-step explanation:</u>

\dfrac{(3x^2y^5)^3}{(2xy^3)^4}\\\\\\=\dfrac{3^3\cdot x^{2\cdot 3}\cdot y^{5\cdot 3}}{2^4\cdot x^4\cdot y^{3\cdot 4}}\\\\\\=\dfrac{27\cdot x^6\cdot y^{15}}{16\cdot x^4\cdot y^{12}}\\\\\\=\dfrac{27\cdot x^{6-4}\cdot y^{15-12}}{16}\\\\\\=\dfrac{27\cdot x^2\cdot y^3}{16}
