<h3>Answer:</h3>

$\frac{1}{9}$

<h3>Step-by-step explanation:</h3>

We know that $x=-2$ , so substitute that into the equation. $y=3^{-2}$

With negative powers, instead of making the result negative, you divide one by it. Mathematically speaking, $x^{-y}=\frac{1}{x^y}$ . This makes our equation: $y=\frac{1}{3^2}$

Finally, simplify the exponent. $y=\frac{1}{9}$

Answer: x^2-9x+1

Step-by-step explanation:

x^2-7x-7 d(x-1)

(you would just replace x to (x-1)

(x-1)^2-7(x-1)-7

(solve by square rooting (x-1)(x-1) then foil)

x^2-9x+1

Could somebody please help me with this?

For this problem, we are going to use the Remainder Theorem. This says that for $x - n$ to be a factor of a polynomial $p(x)$ , then $p(n) = 0$ . Essentially, it says that $x - n$ is a factor if when you substitute $n$ into the polynomial you get a result of 0.

Thus, in our case, when we substitute $x = 2$ into the polynomial, we should get an answer of 0 if $x - 2$ is a factor of the polynomial. Given this information, we can solve for $c$ :
