Answer:
Step-by-step explanation:
Consider the quadratic equation, we have

Dividing the equation by a, we get

Put
on the other side,

Add
on both the sides,

completing the square, we have

Now, solving for x,


Multiply right side by
,

which is the required quadratic formula.
Answer:
P1 = P2 - ma*t
Step-by-step explanation:
ma= P2-P1/t
we multiply by t both sides of the equation
ma*t = (P2 - P1)*t/t
ma*t = P2 - P1
we sum by P1 both sides of the equation:
P1 +ma*t = P2 - P1 +P1
We ave:
P1 + ma*t = P2
we subtract by ma*t both sides of the equation:
P1 + ma*t -ma*t = P2 - ma*t
finally we have:
P1 = P2 - ma*t
I don’t understand the question, it says “if my cost is the same, what should my new price be”, if your cost is the same… there shouldn’t be a new price.I don’t know if this will help but when im trying to find the answer, i use the butterfly method (part over total times percentage over 100).
