Solve the quadratic equations

x^2 -8x + 35 = 0

x^2 +8x + 25 = 0

x^2=8x-35

Step-by-step explanation:

1.1     Factoring  x2-8x+35  

The first term is,  x2  its coefficient is  1 .

The middle term is,  -8x  its coefficient is  -8 .

The last term, "the constant", is  +35  

Step-1 : Multiply the coefficient of the first term by the constant   1 • 35 = 35  

Step-2 : Find two factors of  35  whose sum equals the coefficient of the middle term, which is   -8 .

     -35    +    -1    =    -36  

     -7    +    -5    =    -12  

     -5    +    -7    =    -12  

     -1    +    -35    =    -36  

     1    +    35    =    36  

     5    +    7    =    12  

     7    +    5    =    12  

     35    +    1    =    36  

-18

step-by-step explanation:

because mean value defines that total sum value over total number of set

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
