Anestetic [448]

Answer:

x=16 x=2

Step-by-step explanation:

x^2-18x+81=49

x^2-18x+81-49=0

x^2-18x+32=0

(x-16)(x-2)=0

x-16=0

+16+16

x=16

x-2=0

+2 +2

x=2

11. What is the remainder if x2- 7x - 4 is divided by x<br> - 2? a. 4 b. -14 c. 2 d. -2

<h2>Solving for the Remainder with the Remainder Theorem</h2><h3>Answer:</h3>

$-14$

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

Given:

$x^2 -7x -4$ divided by $x -2$ .

<em>Please refer to my Answer from this Questions to know more about the Remainder Theorem:</em>

<em><u>brainly.com/question/24591570</u></em>
<em><u>brainly.com/question/24591554</u></em>
<em><u>brainly.com/question/24655500</u></em>

Let $P(x) = x^2 -7x -4$ so that when we divide $P(x)$ by $x -\blue 2$ the remainder will be $P(\blue 2)$ according to the Remainder Theorem.

Solving for $P(2)$ :

$P(\blue 2) = (\blue 2)^2 -7(\blue 2) -4 \\ P(\blue 2) = 4 -7(\blue 2) -4 \\ P(\blue 2) = 4 -14 -4 \\ P(\blue 2) = -14$

The remainder is $-14$ .
