Answer 2

(х-12)(х+2)-(х-3)(х+3)=5
х²+2х-12х-24-(х²+3х-3х-9)=5
х²+2х-12х-24-х²-3х+3х+9=5
-10х-15=5
-10х=20
х=-2
ответ: -2

Answer 3

Let's solve the given equation step by step:

Step 1: Expand the expressions on both sides of the equation. (x - 12)(x + 2) - (x - 3)(x + 3) = 5

Expanding the expressions: (x^2 + 2x - 12x - 24) - (x^2 + 3x - 3x - 9) = 5

Simplify the expressions: x^2 - 10x - 24 - (x^2 - 9) = 5

Step 2: Remove the brackets from the equation by distributing the negative sign: x^2 - 10x - 24 - x^2 + 9 = 5

Step 3: Combine like terms on the left side of the equation: (-10x - 24 + 9) = 5

Step 4: Continue simplifying the left side: -10x - 15 = 5

Step 5: Move the constant term to the right side: -10x = 5 + 15

Step 6: Simplify the right side of the equation: -10x = 20

Step 7: Finally, solve for x by dividing both sides by -10: x = 20 / -10

Step 8: Simplify the result: x = -2

Therefore, the solution to the equation is x = -2.
