Solve by completing the square:

x² + 16x + 64 = 13 + 64
(x + 8)² = 77
x + 8 = +/- √77

x = - 8 +/- √77

OR

x = - 8 - √77, - 8 + √77

ASAP PLZ HELP!!
Dominik [7]

Answer:

A) y² - 5y + 1

B) y² - 5y - 4

C) - 5y + 1

D) - 3y² - 4y - 6

Step-by-step explanation:

Let's call P the unkown polynomial and D the difference. In each case, the following must be true:

y² - 5y + 1 - P = D

<em>A)</em>

y² - 5y + 1 - P = 0

y² - 5y + 1 = P

<em>B)</em>

y² - 5y + 1 - P = 5

y² - 5y + 1 - 5 = P

y² - 5y - 4 = P

<em>C)</em>

y² - 5y + 1 - P = y²

y² - 5y + 1 - y² = P

- 5y + 1 = P

<em>D) </em>

y² - 5y + 1 - P = 4y² - y + 7

y² - 5y + 1 - 4y² + y - 7 = P

- 3y² - 4y - 6 = P

____________________________________________

1) 9x - 35 = - 7x + 29

+7x + 7x

_____________________

16x - 35 = 29

+ 35 +35

_____________________

16x = 64

_____________________

16 16

x = 4

2). - 2x - 2 = 9x - 13

+2x +2x

_____________________

- 2 = 11x - 13

+ 13 + 13

_____________________

11 = 11x

_____________________

11 11

1 = x

3). 3x + 29 = - 5x - 27

+5x + 5x

8x + 29 = - 27

-29 -29

_____________________

8x = -56

_____________________

8 8

x = -7

4). x - 11 = 3x - 37

- x - x
