X^2 - 25 = 0
Add both sides by 25
x^2 = 25
Take the positive and negative square root.

x = 5
OR
x = -5

Answer:

there are two solutions are x = (+5) and x = (-5)

Step-by-step explanation:

The given quadratic equation is x² - 25 = 0

Now we can get the solutions of this equation by zero factors.

[ since (a² - b²) = ( a-b ) ( a+b ) ]

so x² - 25 = (x-5) (x+5)

( x-5 ) = 0 ⇒ x = 5

or x + 5 = 0 ⇒ x = -5

Therefore, there are two solutions are x = (+5) and x = (-5)

The operation (5 α 3) + (7 α 5) is 46.

<h3>How to find the amount in the checking account?</h3>

She had 1000 dollars in her checking account. she had a loan of 800 dollars to pay.

After paying her loan form her checking account the balance of the loan reduce to half.

Therefore, she paid 800 / 2 = 400 dollars for her loan

Hence,

Her new checking account = 1000 - 400 = 600 dollars

<h3>How to find value of an operation?</h3>

a α b = ab - a + b

Therefore,

(5 α 3) + (7 α 5)

(5 α 3) = 5(3) - 5 + 3 = 13

(7 α 5) = 7(5) - 7 + 5 = 33

Therefore,

(5 α 3) + (7 α 5) = 13 + 33 = 46

Note: I can't use the at symbol because it is a swear word.
