Some of the students from Millennium Middle School are taking a trip to a museum. In all. fewer than 60 students will go on the trip. The cost for food and admission to the museum is $18 per student. The students will travel on one bus to the museum. The cost of the bus is $800. Complete the table below to show the total cost for food, admission, and the bus for different numbers of students to the museum. (You will need this answer for tomorrow's question)

step-by-step explanation:

x^2 + 81

we can factor this using difference of square binomials.

rewrite the equation:

x^2 - (-81)

factor:

(a^2 - b^2) = (√a^2 + √b^2)(√a^2 - √b^2)

(x^2 - (-81) = (x + √-81)(x - √-81)

we can remove the - from under the radical by multiplying it by i.

(x^2 - (-81) = (x + i√81)(x - i√81)

(x^2 - (-81) = (x + 9i)(x - 9i)

we can check our answer by using foil:

x^2 - 9ix + 9ix - 81i^2

x^2 - 81^2

i^2 = -1

x^2 + 81
