Answer: $3x^6+x^5-x^4-6x^3+x^2+3x-1$

Step-by-step explanation:

(3x^2+x-1)(x^4-2x+1)

=3x^6-6x^3+3x^2+x^5-2x^2+x-x^4+2x-1

=3x^6+x^5-x^4-6x^3+x^2+3x-1

Hope this helps!! :)

Answer:

the thing below xd

Step-by-step explanation:

$(3x^{2} +x-1)(x^4-2x+1)\\\\=3x^2(x^4-2x+1)\\+x(x^4-2x+1)\\-1(x^4-2x+1)\\\\=3x^6-6x^3+3x^2\\+x^5-2x^2+x\\-x^4+2x-1\\\\=3x^6+x^5-x^4-6x^3+(3-2)x^2+(1+2)x-1\\\\=3x^6+x^5-x^4-6x^3+x^{2} +3x-1$

Polynomial equation is a equation which is formed with coefficients variables and exponents with basic mathematics operation and equality sign. The given option the option A matches correctly with the above polynomial equation which is,

$-7xy^3+8x^2y^2-\dfrac{3x^3y}{2}+4x^4$

Hence the option A is the correct option.

<h3>Given information-</h3>

The given polynomial equation in the problem is,

$8x^2y^2-\dfrac{3x^3y}{2}+4x^4-7xy^3$

<h3>Polynomial equation </h3>

Polynomial equation is a equation which is formed with coefficients variables and exponents with basic mathematics operation and equality sign.

In the above polynomial equation the variable are<em> x </em>and <em>y </em>and the highest power of the variable <em>x</em> is four and highest power of the variable <em>y</em> is three.

Arrange the polynomial equation in the power of the variable <em>x. </em>Thus,

$4x^4-\dfrac{3x^3y}{2}+8x^2y^2-7xy^3$

Arrange the polynomial equation in the power of the variable <em>y. </em>Thus,

$-7xy^3+8x^2y^2-\dfrac{3x^3y}{2}+4x^4$

From the given option the option A matches correctly with the above polynomial equation which is,

$-7xy^3+8x^2y^2-\dfrac{3x^3y}{2}+4x^4$

Thus the option A is the correct option.

Ok, first you need to read a - g and mark down the information you know. Also, this continuous function can look pretty much like anything long as it has the a - g constraints/rule.

A) We know the domain(x values) is between -10 to infinity
(-10,-9,-8,-7,-6,-5,-4,-3-,2,-1,0,1,2,3,4,5,6,7,8,9,10, to ---------> infinity)
B) We know the range(y values) is between -6 to infinity
(-6,-5,-4,-3-,2,-1,01,2,3,4,5,6,7,8,9,10, to ---------> infinity)

C) Next we know f(0) = f(4) = 0
So we know when x = 0 that f(0) = 0 or we can say y = 0. We also know when f(4) = 0 so when x = 4 y = 0. So we have two points (0,0) and (4,0) that our function will be on so plot the two points (0,0) (4,0)

D) It tells us that f(x) (y) is increasing between the x values (-10,-6) or (-2,2) or (4, to infinity)

E) It tells us that f(x) (y) is decreasing between the x values (-6,-2) or between (2,4)

F) Tells us that f(x) (y) is greater than or equal to between the x values of [-8,-4] or between the x values [0, to infinity) so this lets us know our drawing is going to be above or equal to 0 when we are in the values [-8,-4] or [0, to infinity)

G) Tells us that f(x) (y) is less than 0 when the function / drawing is between the x values of (-10, -8) or (-4,0)

The picture is what the function could look like. It can be different but needs to following the rules that are given
