Question

10x(5x + 2) = 60 - 2x( - 25x - 5)​

Answer 1

50х^2+20х=60+50х^2+10х
50х^2 и -50х^2 сокращаем, остаётся
20х= 60+10х
20х-10х=60
10х=60 |:10
х=6

Answer 2

To solve the equation 10x(5x + 2) = 60 - 2x(-25x - 5), you'll need to simplify and solve for the variable x. Let's break it down step by step:

1. Distribute on both sides of the equation:

   10x * 5x + 10x * 2 = 60 + (2x * 25x) + (2x * 5)

2. Simplify each term:

   50x^2 + 20x = 60 + 50x^2 + 10x

3. Subtract 50x^2 from both sides to cancel out the quadratic terms:

   20x = 60 + 10x

4. Subtract 10x from both sides to isolate the x terms:

   20x - 10x = 60

5. Simplify:

   10x = 60

6. Finally, divide both sides by 10 to solve for x:

   x = 60 / 10 x = 6

So, the solution to the equation is x = 6.
