Объяснение:

(x-5)²-(x-3)(3+x)=34​

(x-5)²-(x-3)(x+3)=34​

x²-2x*5+5²-(x²-3²)=34

x²-10x+25-x²+9=34

-10x+34=34

-10x=34-34

-10x=0

x=0:(-10)

x=0

Answer 2

To solve the equation, let's simplify and expand the terms:

(x - 5)² - (x - 3)(3 + x) = 34

Expanding the squared term:

(x - 5)(x - 5) - (x - 3)(3 + x) = 34

(x² - 10x + 25) - (3x + 3x - 9) = 34

x² - 10x + 25 - 3x - 3x + 9 = 34

Combine like terms:

x² - 16x + 34 = 34

Now, subtract 34 from both sides:

x² - 16x = 0

Factor out x:

x(x - 16) = 0

Now we have two possible solutions:

1. x = 0
2. x - 16 = 0

For the second equation, solve for x:

x - 16 = 0 x = 16

Therefore, the solutions to the equation (x - 5)² - (x - 3)(3 + x) = 34 are: x = 0 and x = 16.
