There's a lot of ways! So, you can plug in and solve, solve for the two roots, solve for the vertex form, and solve for the standard form. Multiple ways!
Answer:
the coefficients are 4 and 5 and 1
Step-by-step explanation:
the 4 and 5 have a variable in front of them. There's a ghost 1 in front of the x, because it's value is 1 times whatever the value of x is
How would we do that here
Answer:
3(2 + x)
Step-by-step explanation:
You have to multiply 3 by the sum of 2 and any number, or x. So if you put the expression of 2 + x in parenthesis, and 3 next to it. You'll get your answer.
Answer:
600 seats
Step-by-step explanation:
We know there is 120 seats on a balcony and that is 
of the total seats, we want to find the total number of seats so,
120 seats =
We know that a whole fraction sums to 1 so for example 
120 seats =
Multiply both sides to make it a whole fraction
600 seats = 
So if there is 120 seats and that number is only of the total number of seats then the total number of seats is 600
