To find the zeros, set y = 0
Now try to isolate the (x-4)^2 term (move 10 to right side, divide by -5)
Next take square root of both sides (this cancels the square on (x-4))
For interpretation, x = price, y = profit
We are solving for price where profit = 0.
1/2 plus 1/3 is 5/6.
You have to find the common denominator
Answers:
- Number of terms: 5
- Coefficients: 4, 4, -5 and 1
- Constant term: 3
===================================================
Explanation:
Each term is separated by a plus sign or a minus sign. We could rewrite the 4ab-5b portion as 4ab + (-5b) to help get everything separated by a plus sign.
The five terms are
The coefficients are the numbers just to the left of the variable. For a term like 4ab, the coefficient is 4. For the term "m", we can think of it as 1m so we can see it has a coefficient of 1.
The constant term is the term that doesn't have any variable attached to it. That would be the "3" as the first term.
Associative property of multiplication
(note, ab means a times b)
a(bc)=(ab)c
allows us to move parenthasees around when all multiplying
