Answer:

x = -1, x = 1

Step-by-step explanation:

Factor the equation. (It's a difference of squares, so we know the form will be (a-b)(a+b).)

$y = x^{2} - 1\\y = (x-1)(x+1)$

Test this by FOILing it out, if you're unsure. This is something it can be good to memorize!

Set it equal to 0.

$0 = (x+1)(x-1)$

Separate the two parenthetical expressions by the Zero Product Property.

$0 = x+1\\0 = x-1$

Solve for x!

$x=-1, x=1$

Last fall, a middle school took a group of students on a trip to Space Camp, which is 360 miles away. The bus that they took to

mezya [45]

Answer:

The bus travelled 60 miles in 1 hour.

Step-by-step explanation:

To solve this problem we need to calculate the average speed at which the bus travelled. This is given by the distance travelled divided by the time that they took to get there. So we have:

average speed = distance/time

average speed = 360/6

average speed = 60 miles/h

Therefore in 1 hour they travelled 60 miles.
