Answer:
x =
± 
Step-by-step explanation:
Given
x² - 7x + 9 = 0 ( subtract 9 from both sides )
x² - 7x = - 9
Solve using the method of completing the square
add ( half the coefficient of the x- term)² to both sides
x² + 2( -
)x +
= - 9 +
(x -
)² =
( take the square root of both sides )
x -
= ±
= ±
( add
x =
±
=

Step-by-step explanation:
8(9x-11)
72x-88
If you were trying to simplify it, it's not posible because 23 is a composite number so I just went ahead and did division for you:
23/46=0.5
I hope this helped!
