A General Note: Perfect Square Trinomials A perfect square trinomial can be written as the square of a binomial:
a2+2ab + b2=(a + b)2
and
a2-2ab +b2= (a - b)2
The factoring techniques of grouping or trial and error still work on perfect square trinomials
Given a perfect square trinomial, factor the trinomial into the square of a
binomial.
1. Confirm that the first term and third term are perfect squares.
2. Confirm the middle term is equal to 2ab.
3. Write the trinomial in the factored form (a + b)2or (a - b) 2 based upon
the sign of the middle term.

the answer is (-4,-4)

hope this ! : d

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
