need help with math build an equation that is equivalent to the equation k=19 and also put answer in words

Given the quadratic functions expressed as;

x² - 6x = 12

The value of p given the quadratic expression is -3

Complete the square at the left hand side of the equation.

Add the square of the half of coefficient of x to both sides.

coefficient of x = -6

Half of coefficient of x = -6/2 = -3

Square of the result = (-3)² = 9

Add 9 to both sides of the equation

x² - 6x + 9 = 12 + 9

Factoring the left hand side

(x-3)² = 21

Comparing the result with (x+p)² = q

The value of p wil be -3

Answer:

p = - 3

Step-by-step explanation:

Given

x² - 6x = 12

To obtain the required form use the method of completing the square

add ( half the coefficient of the x- term )² to both sides, thus

x² + 2(- 3)x + 9 = 12 + 9

(x - 3)² = 21

Thus p = - 3

Square have 4 equal sides length = a

A = 255  

A = a^2

255 = a^2   |sqrt

15 = a

P = 4a  

P = 4*15 = 60

→ The way I like to do these kind of math problems is below - I find it easier

A fraction usually means to divide, so I will start by dividing the numerator by the denominator of 7/10.

7/10 = 0.7, or, 70%

1/5 = 0.2, or, 20%

Now, we can go and divide each of our answers together.

0.7 ÷ 0.2 = 3.5 :D

Your final answer is 3.5
