When we answer a question, the hope is always that you will learn something. Even if you don't we hope you can, at least, copy the steps using different numbers as may be required. See brainly.com/question/8683122.

1) subtract the constant (23)
.. x^2 -10x = -23

2) determine the coefficient of the x term (-10)
3) figure the value of half that (-5)
4) compute the square of that value ((-5)^2 = 25)
5) add that square
.. x^2 -10x +25 = 2

6) rewrite the left side as a square (you have chosen the correct form)
.. (x -5)^2 = 2

_____
To solve,
7) take the square root of both sides of the equation.
.. x -5 = ±√2

8) add the opposite of the constant on the left
.. x = 5 ±√2

Bus A and Bus B leave the bus depot at 8 am.
LenaWriter [7]

Answer: 10:55

Step-by-step explanation:

Taking statement at face value and the simplest scenario that commencing from 08:00am the buses take a route from depot that returns bus A to depot at 25min intervals while Bus B returns at 35min intervals.

The time the buses will be back at the depot simultaneously will be when:

N(a) * 25mins = N(b) * 35mins

Therefore, when N(b) * 35 is divisible by 25 where N(a) and N(b) are integers.

Multiples of 25 (Bus A) = 25, 50, 75, 100, 125, 150, 175, 200 etc

Multiples of 35 (Bus B) = 35, 70, 105, 140, 175, 210, 245 etc

This shows that after 7 circuits by BUS A and 5 circuits by Bus B, there will be an equal number which is 175 minutes.

So both buses are next at Depot together after 175minutes (2hr 55min) on the clock that is

at 08:00 + 2:55 = 10:55
