X^2 + 6x = 13. We are to "complete the square."
x^2 + 6x + (6/2)^2 - (6/2)^2 = 13
Then (x+3)^2 - 9 = 13, or (x+3)^2 = 22.
then x+3 = plus or minus sqrt(22), or x = -3 plus or minus sqrt(22).
Given x^2 + 6x = 13, to complete the square we insert " 3^2 - 3^2 " between the "6x" and the "=" sign.
Add 10 to 33=43 there for he will run 43 minutes on Sunday because the pattern in adding by 5 each day
Answer:
x= -1
Step-by-step explanation:
Given data
We have the expression as
(x+1)/(x+1)= 1/2
let us first cross multiply
2(x+1)=(x+1)
2x+2=x+1
collect like terms
2x-x=1-2
x= -1
Hence the value of x=-1
