Follow the process of completing the square to solve x2 - 10x + 8 = 0. how will the left side of the equation factor in step 5? a. (x - 10)2 b. (x - 20)2 c. (2x - 10)2

(2x-10)^2

Step-by-step explanation:

Follow the process of completing the square to solve x^2 - 10x + 8 = 0

First we subtract 8 from both sides

x^2 - 10x = -8

In completing the square method we take half of coefficient of middle temr -10x  and then we square it

-10/2 = -5

(-5)^2= 25

Now we add 25 on both sides

x^2 - 10x +25 = -8+ 25

x^2 - 10x +25 = 17

Now we factor the left hand side x^2 -10x+25  

We take half of middle term -10/2  

(x-10/2)^2 that is (2x-10)^2

So the left hand side of the equation factor is (2x-10)^2

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
