1. what is the vertex form of the equation? 2. what is the expression in factored form? 3. use the quadratic formula to solve the equation. 4. simplify the expression.

1.vertex form is

to get into vertex form, complete the square

step 1: group x terms

step 2: factor coefient in front of x^2 term

prep for next step: take 1/2 of linear (1st dgree term) and square it

,

step 3: add positive and negative of that previous number inside the parenthasees

factor perfect squaer trionmial

take out that -36 by expansion

2. factor out the 2

what 2 numbers multiply to get 12 and add to get 8?

2 and 6

3.

for

in our case

a=1, b=-7, c=-6

so and

4. remember that so

treat as a variable

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
