Answer:

Step-by-step explanation:

Since you are dealing with x's in one term and y's in the other, the only thing you can factor out is whatever number is common to both 15 and 10. That happens to be a 5. Therefore,

$5(3x^7+2y^2)$

is the simplest this can get.

<em>The zeros of the polynomial are -1 and 5</em>

Step-by-step explanation:

<u>Quadratic Equation Solving</u>

The standard representation of a quadratic equation is:

$ax^2+bx+c=0$

where a,b, and c are constants.

Solving with the quadratic formula:

$\displaystyle x=\frac{-b\pm \sqrt{b^2-4ac}}{2a}$

We have the following equation to solve:

$x+x^2-5x-5=0$

Before attempting to solve it, we must simplify the equation.

Collecting like terms and reordering:

$x^2-4x-5=0$

Here: a=1, b=-4, c=-5

The discriminant of this quadratic equation is:

$d=b^2-4ac$

$d=(-4)^2-4(1)(-5)=16+20=36$

Given d is positive, the equation has two roots, and since d is a perfect square, both roots are rational.

Applying the formula:

$\displaystyle x=\frac{4\pm \sqrt{36}}{2(1)}$

$\displaystyle x=\frac{4\pm 6}{2}$

Dividing by 2:

$x=2\pm 3$

Separating both roots:

x = 2 + 3 = 5

x = 2 - 3 = -1

The zeros of the polynomial are -1 and 5

Which expression is equivalent to the quantity five raised to the negative second power times three raised to the fifth power en

serg [7]

The equivalent expression is 5^(4) * 3^(-10)

<h3>How to determine the equivalent expression?</h3>

The statement is given as:

five raised to the negative second power times three raised to the fifth power end quantity all raised to the negative second power

Rewrite properly as:

(5^-2 * 3^5)^-2

Expand the expression by multiplying the exponents

So, we have:

5^(-2 -2) * 3^(5 *-2)

Evaluate the products

5^(4) * 3^(-10)

Hence, the equivalent expression is 5^(4) * 3^(-10)
